An efficient and exhaustive standard-cell abutment verification tool is developed to ensure 100% layout verification coverage of design rule check (DRC) on boundaries created by standard-cell abutment during placement, Vt swap and ECO (engineering change orders). Several case-reduction techniques are presented to remove the redundancy of duplicate abutment. This methodology can achieve one order-of-magnitude reductions in the test area to exercise all boundaries created by all placement permutations in standard cell libraries.

Carrier aggregation (CA) in latest 4G standards and beyond demands either multiple narrow-band RX branches or a single wide-band RX branch followed by efficient channelizer architectures in the digital front-end (DFE). The small number of simultaneously received component carriers favors the use of a single wide-band ADC in conjunction with a per-channel carrier extraction. However, the computational complexity of the digital extraction is high due to the mixing operation for each of the aggregated carriers. In this work, we show how the complexity of the per-channel approach can be reduced by employing DFE architectures using cascaded integrator comb (CIC) based filter stages. Promoting a joint configuration approach for the ADC and subsequent filter stages, the different low-complexity filter architectures are analyzed, evaluated and compared. By an LTE-Advanced non-contiguous CA design example, the feasibility of the addressed designs is demonstrated and the approach with the best performance-complexity trade-off is identified.

A wireless power delivery system for a biomedical retinal prosthesis is presented and analyzed. Due to large and fast coupling variations in the inductively powered retinal implant caused by the eye movements, excessive power has to be controlled. This power delivery setup enables excessive power control measurements by featuring movements of an eye model. The turning of the eye model is controlled with a microcontroller board. Measurements and control of the model is automatized using Matlab. Measurement results show an enormous reduction of the transmitted power for large eye movements and therewith the need for power control in biomedical implants.

This paper investigates a hybrid technique that uses a combined version of Received Signal Strength (RSS) and Direction of arrival (DOA) localization techniques. Simulation results prove that using the hybrid technique in one node increases the localization accuracy and provides the node with the capability of localizing other nodes by itself without any assistance from other nodes. The performance of the hybrid technique has been evaluated under both Additive White Gaussian Noise (AWGN) and Rayleigh channel conditions. Moreover, the study shows when to use the hybrid node, and where to place such node in a given environment to get the optimum results.

With the rapid expansion of major cities, the tremendous increase in the number of vehicles, and the construction of huge buildings and parking areas, there is a need to develop smart parking systems to assist drivers finding the nearest available parking spots. Such systems have witnessed substantial research efforts in developed countries. There are mainly four categories of car parking management systems: counter-based, wired-sensor-based, wireless-sensor-based, and image-based. In this paper, we develop, implement, and test an image-based system for the detection of vacant spaces in a parking area. Following an initial edge detection stage, we combine edge density, closed contour density, and foreground/background pixel ratio, at every car parking spot, to identify whether a car is present or not. Combining the features above results in a robust vacant space detection system at low computational cost.

The growing interest in multimedia applications can cause bandwidth scarcity problem in server-client based architectures, making P2P a promising alternative. Bit-Torrent is one of the most popular P2P solutions and there have already been propositions to tune it for video streaming. In this study, a torrent based P2P video streaming solution is used. scalable video coding (SVC) streaming is realised in an adaptive video streaming framework. Moreover, we evaluate two most well renowned SVC codecs namely MPEG SVC and Wavelet based SVC and compare their rate-distortion performances both before and after video streaming. Extensive simulations have been performed to investigate the effect of increasing number of layers in SVC.

Piezo Electric (PE) harvesters have been of recent interest because they provide a clean and free source of energy. PE is suitable for many applications, especially in wearable healthcare applications where the healthcare device can harvest its needed power, and sense vital signs from the human body. A special interface circuit is needed to extract power from the PE, such as the AC-DC converter. In this paper, we will present a study of the PE harvester and its suitability for low-power applications. Furthermore, a survey of the common interface circuit topologies used in AC-DC converters for PE based systems will be presented. In addition, comparisons between these interface circuits in terms of efficiency, area overhead, and design complexity will be discussed.

IPv6 was introduced but yet it is not widely used. Research work has been pointed to many directions, specifically, on how to migrate from IPv4 to IPv6, on how to adapt hardware devices to support a transitory period from coexistence between IPv4 and IPv6 to established use of IPv6, and on how should operating systems perform when using IPv6 as compared to IPv4. This work provides a comparative performance evaluation between IPv6 and IPv4 in wireless networks under Windows 7, Linux “Fedora 16”, and Mac OS platforms. Throughput, round trip time and percentage CPU usage are the metrics adopted for the evaluation.

In high-speed communication systems, adaptive equalizers are widely applied to improve signal integrity in both master chip and slave chip. In this paper, a novel architecture with adaptive equalizers applied only in the master chip is proposed for the low-power design through adaptive equalizer trainings. Focused on the transmitter equalizer training, results show that proposed pilot signal/peak detection algorithm can dramatically improve the signal quality with small area and reasonable training time, but it has the limitation in canceling the inter-symbol interference caused by the pre-cursor of the channel.

Cooperative diversity is widely used in the new emerging wireless communication systems. In this paper, the average error rate performance of Cooperative Maximum Ratio Combing (CO-MRC) receiver is analyzed over generalized statistically-measured fading channels. The diversity links are assumed to be independent but not necessarily identically-faded. The general CO-MRC SNR-PDF is simulated for different values of the average Signal-to-Noise Ratio (γo). Then, the SNR-PDF expression is utilized to derive a closed-form expression for the approximated average error rate using different coherent modulation techniques. Monte Carlo simulation results are presented to validate the SNR-PDFs and the derived average error rate expressions.
