It is shown that enhanced UMTS is an affordable solution for providing the required network quality and to reduce infrastructure investments in offices scenarios. System capacity results are obtained by using a system level simulator which considers traffic characterisation parameters and services usage in detail, among other. Results for the most profitable cell radius are obtained via an optimisation procedure based in economic aspects. A higher number of pico cells (with a smaller radius, around 30-32 m) can be installed in the future, when costs of deploying and maintaining the network decreases, allowing for supporting higher system capacity, and reducing prices. Our approach is based in a detailed services analysis, which represents a worst case situation relatively to the total services approach, because the later does not discriminate results for the different traffic classes. The impact of call blocking, handover failure, end-to-end delay, and delay variation are taken into account

In this paper we present and evaluate a low cost simple method for accurate time of arrival (TOA) estimation in multipath fading channels for positioning purposes. It is well known that TOA estimations are biased in multipath propagation and non-line-of-sight (NLOS) conditions. These biases will result in poor position estimations in wireless networks. Recently super-resolution methods have been widely used for high resolution TOA estimations. Although these methods result in accurate TOA estimates, but they need strong processors that in many cases makes them impractical. Here, using time domain properties of the estimated channel delay profile, we introduce a simple method to reduce the TOA estimation errors due to the multipath fading channels. In order to evaluate the proposed method, we simulate a UMTS network based on 3GPP standards. The positioning error using the proposed method will be compared with the ones obtained by MUSIC algorithm which is a famous and accurate super-resolution method. Simulation results show the effectiveness of the proposed method

In order to achieve high decoding throughput (hundreds of MBits/sec and above) for multiple code rates and moderate codeword lengths, several LDPC decoder solutions with different levels of processing parallelism are possible. Selection between these solutions is based on a threefold criterion: hardware complexity, decoding throughput, and error-correcting performance. In this work, we determine the multi-rate LDPC decoder architecture with the best tradeoff in terms of area cost, error-correcting performance, and decoding throughput. The prototype architecture of this decoder is implemented on an FPGA

In next generation wireless networks mobility management is a severe problem that needs careful attention, in order to achieve inter-working of Internet with wireless networks, and to meet the requirement of seamless handoff for real-time and multimedia applications. Advanced mobility support is required to effectively deal with the challenges that mobility poses. Single layer-specific mobility management architectures can hardly provide advanced mobility support required in future all-IP wireless networks. Advanced mobility support calls for a coordination of layers through a well defined cross layer platform to achieve better performance. We propose a mobility scenario driven mobility management architecture that exploits cross layer design in wireless terminals to provide seamless terminal mobility in future all-IP wireless network. Each mobility scenario uses a specific cost function that incorporates parameters necessary to support handoff decision in that particular environment

The use of lattice reduction (LR) has been shown to be a very effective method for signal detection in multiple antenna systems. In this paper, the performance of the sub-optimal soft-output maximum a posteriori (MAP) detector with lattice reduction is studied in multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) system. We propose two polynomial-time methods to generate the desired size candidate list in the reduced lattice. The sub-optimal soft-output MAP detector with these list generation methods provides a near-optimal performance in uncorrelated MIMO-OFDM systems, but with significantly reduced computational complexity

This paper presents an innovative solution to reduce the total cost of ownership (TCO) for mobile users in growth markets. This specifically addresses countries with a large variety of average revenue per user (ARPU). Instead of a traditional, homogeneous subscriber base, the new concept enables the operator to offer service quality depending on a subscription class chosen by the subscriber. This way, a high-income, high-ARPU segment can expect top service quality ("no call blocking or dropping"), while low-income, low-ARPU subscribers, who previously were not able to afford any kind of mobile services, will experience a "best effort" type of service, with high service quality most of the time but increased call blocking rates and vulnerability to pre-emption during busy hours. The higher ARPU from high-class subscribers and the generation of additional low-ARPU subscribers are expected to generate ca. 50% higher revenue for the operator. Capacity upgrades show an immediate return on investment (ROI). Due to its still dominant position in the market share of mobile services, GSM voice calls are the main focus of this work

In this manuscript, an interferential packet detection scheme in IEEE 802.11 WLANs is proposed. If another basic service set (BSS) is overlapping domestic BSS, some stations (STAs) may suffer from interference from a hidden terminal in overlapping BSS (OBSS). One of the best ways to avoid this undesirable situation is channel switching after detecting OBSS. However there are some difficulties to recognize existence of OBSS. One difficulty is that STAs in domestic BSS can't receive frames from OBSS correctly and can't check BSSID of frames if traffic in domestic BSS is heavy and if transmission rates of frames from OBSS are higher. Another difficulty is that if the cell radius of domestic BSS is smaller than that of OBSS, some STAs in OBSS may transmit frames asynchronously and interfere with transmissions in domestic BSS. If interference causes frame error, domestic STA can't distinguish interference from degradation of channel condition. This paper proposes a method whereby STAs can detect interferential packet even while STAs receive frames from domestic BSS. If STAs detect interference, channel switching is performed dynamically. The probability of detecting interferential packets is evaluated by computer simulation, and the results confirm the effectiveness of the proposed method

In this paper, we investigate and propose the detection techniques for spatially layered multiple-input multiple-output (MIMO) multi-carrier code division multiple access (MC-CDMA) systems. First, we propose a noise-predictive linear detector. It has the same bit error rate (BER) performance as symbol-level detector and reduces the complexity significantly when the system load is almost full. We also propose a partial minimum mean square error (MMSE)-ordered successive interference cancellation (OSIC) based on multi-user detection, which first detects the most powerful interfering data symbols transmitted through the determined transmit antenna and then cancels their contribution from the received signal by the multiplexed data symbol vector. The nulling and cancelling processes between the user data symbols from the same transmit antenna are not performed. The proposed algorithms are verified by computer simulation

The upcoming IEEE WiMax 802.16e standard, also referred to as WirelessMAN (2005), is the next step toward very high throughput wireless backbone architectures, supporting up to 500 Mbps. It features as an advanced channel coding scheme low-density parity-check codes. The decoding of LDPC codes is an iterative process, hence many data have to be exchanged between processing units within each iteration. The variety of the specified codes and the envision of different decoding schedules for different codes pose significant challenges to an LDPC decoder hardware realization. In this paper, we present to the best of our knowledge the first published LDPC decoder architecture capable to process all specified WiMax LDPC codes.
