chapter
Orthogonal frequency division multiple access (OFDMA) and Single Carrier Frequency Division Multiple Access (SC-FDMA) are the two major multiple access schemes for 4G wireless communications. In long term evolution (LTE) the downlink multiple access scheme is based on OFDMA and the uplink multiple access scheme is based on SC-FDMA. In this letter, we derive the fundamental performance difference between...
chapter
Singular value decomposition and Akaike information criterion based image enhancement is proposed for through wall imaging. Akaike information criterion is used with singular value decomposition to find spectral images belonging to targets. Simulation results compared on the basis of mean square error, peak signal to noise ratio, miss detection, false detection and visual inspection show the significance...
chapter
High signal peak values are one of the fundamental obstacles to greater efficiency in wireless communications systems. There exist many techniques to reduce signal peak values; however, there have been few theoretical studies of the trade-off between reducing peak values and the resulting cost in other resources. Here we address the trade-off between peak reduction and information rates for two standard...
chapter
In this paper, we review the signal-to-leakage-plus-noise ratio (SLNR) transmit precoding criterion and the active antenna selection (AAS) strategy in a multi-user MIMO system. We then address the limitations of the original SLNR and AAS schemes and provide a solution that generalizes the SLNR precoding model by incorporating the antenna-receiver structure into the optimization process to further...
chapter
This paper addresses the problem of sparse channel estimation in the context of Orthogonal Frequency Division Multiplexing (OFDM) systems. We propose to extend a recently proposed tap-tuned threshold-based Channel Impulse Response (CIR) structure detection scheme to the case of fast varying channels, through the use of a uniform pilot subcarriers placement. The chosen thresholds minimize the estimation...
chapter
Broadcasting systems have to deal with channel variability in order to offer the best spectrum efficiency to the receivers. However, the transmission parameters that optimize the spectrum efficiency generally leads to a large link unavailability. In this paper, we study the performance of hierarchical and non-hierarchical modulations in terms of spectrum efficiency and link unavailability for DVB-S2...
chapter
For multiuser multiple-input multiple-output (MU-MIMO) systems with limited feedback in the downlink scenario, an end-to-end robust Tomlinson-Harashima Precoding (THP) transceiver design that incorporates receiver combining and transmit precoder is proposed based on sum mean squared error (SMSE) minimization. The channel state information (CSI) available at the transmitter for precoding is the quantized...
chapter
Spectral efficiency (SE) is one of the key performance indicators of wireless communications, and energy efficiency (EE) is an urgent need to tackle the challenges raised by the high demands of wireless traffics and energy consumption. However, these two important design criteria conflict with each other and a careful study of their trade-off is mandatory for designing future wireless communication...
chapter
The development of self-management solutions for (multi-technology, multi-layer) mobile communication networks is driven by their increasing operational complexity. Initial stand-alone SON (Self-Organizing Networks) solutions are already available, but are not sufficient to handle the networks of tomorrow. In this paper we present our approach at developing a unified management framework that integrates...
chapter
This paper assumes a practical channel model, called a cascaded Rayleigh fading channel, for a noncooperative distributed mobile relay network, which consists of one mobile source and one mobile destination, and multiple mobile amplify-and-forward (AF) relays. Then, an optimum AF relay amplifying vector (or matrix) is analytically designed using the minimum mean square error (MMSE) criteria and uses...
