Since IEEE has standardized 802.11 protocol for WLANs, significant work has been done in developing rate adaptation algorithms. Most of the rate adaptation algorithms proposed till now are heuristic, suboptimal and are competitive in nature. Even though these algorithms have advantage of implementing in distributed fashion, their throughput performance will be low as these schemes may converge to inefficient Nash equilibrium [1]. On the other hand users may cooperatively choose their rates so that a social optimum can be achieved, but there are no known algorithms that do rate adaptation cooperatively and still be implemented in a distributed fashion. In this paper, we aim at designing a distributed algorithm that achieves a social optimum (by doing rate adaptation cooperatively) while guaranteeing proportional fairness. We also propose an efficient centralized algorithm which serves the same purpose as the distributed algorithm.

To achieve high data rates and seamless coverage, radio access networks continue to increase in complexity, and the expenditure on operational tasks continues to rise to unprecedented levels. The development of Long Term Evolution (LTE) with Self-organizing network (SON) functions is being considered as an effective way to tackle these challenges. The paper describes an approach to model the coverage areas so that resource allocation algorithms can benefit from traffic distribution and coverage information. The main problem considered in this paper is the partitioning of the wireless environment into regions that allow for accurate modelling of the propagation environment and prediction of the traffic distribution. The analysis is based on models constructed from historical data and monitoring of the received signal strengths from the mobile stations (MSs). The mechanism is based on the similarity of perceived signals from MSs. The performance is evaluated using data generated from a network planning tool for a real environment.

We consider a reuse-1 cellular system and study the improvement in SINR possible for a fixed/nomadic receiver, from the use of an optimally oriented directional patch antenna or a Uniform Linear Array (ULA) with 2 or 4 antenna elements along with Minimum Mean Square Error (MMSE) combining. We perform the studies with a ray-tracing propagation model as well as an empirical statistical model that is based on measurement values, in an urban macro scenario. The results show that a mean improvement of around 5 dB in SINR is possible using either the directional antenna or a 2-antenna ULA. In contrast, a 4-antenna ULA gives a mean improvement of around 11 dB. Interestingly, the results are similar with both channel models.

A p-n junction under reverse bias avalanche breakdown condition is capable of producing high frequency rf power in Impatt mode. With the advancement of Device Technology, the present state of art reports realization of alloy Si-Ge junction, Si-Ge hetero junction. Introduction of a n-Ge and p-Ge impurity bumps near the junction face on respective side of Si p-n junction leaves an asymmetrical hetero structure junction which has become the scope of study of this paper for operation at 15 and 96 GHz. Three tier sophisticated computer algorithm has been framed and used for Impatt analysis of resulting n-Si-Ge/p-Ge-Si Hetero Structure reveals realization of device efficiency as high as 29.6% (Theoretical Optimum Efficiency of Impatt Diode=31%) and also high value of negative conductance. Presence of Ge layer near junction and an order high carrier ionization rate in Ge compared to Si localizes the avalanche zone, which pushes the efficiency and RF power generation. Similar results are also noticed for 96 GHz operations. The performance from this structure is observed to be superior by considerable extent as compared to Si and Ge homo structure. However the complementary hetero structure having the form n-Ge-Si/p-Si-Ge is observed to exhibit performance almost on par to Si and Ge homo structures. The results are highly encouraging which may make Si-Ge Hetero Structure Diode as a microwave generator.

We propose a maximum a-posteriori (MAP) based blind algorithm for carrier frequency offset (CFO) and symbol timing offset (STO) estimation, for a convolutionally coded orthogonal frequency division multiplexing (COFDM) system, in an additive white Gaussian noise (AWGN) channel. We derive the MAP estimators mathematically. It is observed that though the MAP metric for CFO estimation gives a good performance for an AWGN channel, the MAP metric for STO estimation is unable to provide satisfactory performance.

This paper proposes a novel scheme for the spatial rendition of audio in a teleconferencing situation. Several researchers have examined and established that there is a substantial improvement in intelligibility by the use of spatialization in such a multitalker environment, over monaural rendition. We provide experimentally obtained values for the Minimum Audible Angle (MAA) that provides release from masking in a speech over speech masking scenario. The results clearly indicate that the MAA varies with the azimuth. This dependency on azimuth has been utilized to improve the intelligibility of speech in a given teleconference within a limited auditory space. The advantage of such a scheme over simple auditory space division is demonstrated by another set of perceptual experiments.

Exact expressions are obtained for the bit error rate (BER) for coherent and noncoherent decode and forward (DF) cooperative systems with two relays. The piecewise linear (PL) combiner, a close approximation to the maximum likelihood (ML) detector, is employed at the receiver. BER analysis is done using a contour integral approach for evaluating the Gil-Pelaez integral involving the characteristic function (CF) of the decision variable. Previous attempts relied on a direct approach, that imposed restrictions on the location of the relays. In this paper, this restriction has now been removed. Through simulation results, we verify the validity of the derived analytical expressions.

In a distributed control wireless ad hoc network, multi-user interference plays a significant role in determining one-to-one communication throughput performance of the network. Although the effects of exposed/hidden terminals on the network throughput in a single-channel wireless ad hoc network have been extensively studied, the interference power computation at the receiver and its effect on the acceptable communication range has not been analyzed in the literature. In this paper, via probabilistic analysis we capture the total interference power that a receiver node experiences. We then demonstrate the impact of interference power on the effective communication range of the nodes. Our analytic results are validated by C-based network simulation. The observations in this paper can be used in deciding interference-aware multi-hop forwarding strategies in wireless ad hoc networks.

This paper presents a first order Takagi-Sugeno-Kang (TSK) type fuzzy equalizer to mitigate nonlinear power amplifier distortion effects from the received signal in orthogonal frequency division multiplexing (OFDM) systems. Here we propose a Comprehensive Learning Particle Swarm Optimizer (CLPSO) [1] based structure identification of the TSK equalizer. CLPSO uses a new learning strategy that achieves the goal to accelerate the convergence of the classical particle swarm optimization (PSO) to the global optimal values. Unlike gradient based techniques CLPSO has the capability to escape from the traps of local optima while obtaining the values of nonlinear premise parameters of TSK equalizer. In this work, proposed equalization technique reduces the adverse nonlinear distortion effects at receiver in a Rayleigh faded OFDM communication system and a significant improvement in bit error rate (BER) performance is achieved. Computer Simulations show improved bit error rate (BER) and mean square error (MSE) performances of this novel PSO based TSK equalization in OFDM receiver compared to the latest power amplifier nonlinearity cancellation (PANC) technique [2].

This paper presents a single stage low-noise amplifier (LNA) using cascode topology for low-power UWB applications. Resistive feedback is used to obtain large bandwidth. The LNA achieves peak gain of 11.8 dB and noise figure varying from1.72 – 3.62 dB within the band of 3.1 – 10.6 GHz. The LNA uses supply of 2 V while consuming only 6 mW of dc power. The technology used for design is 0.25 µm IHP SiGe BiCMOS which employs Heterojunction Bipolar Transistor (HBT). The output 1 dB compression point and input IP3 for LNA are −23 dBm and −12.48 dBm respectively.
