The efficient high-throughput VLSI implementation of near-optimal multiple-input multiple-output (MIMO) detectors for MIMO systems with large number of antennas in high-order quadrature amplitude modulation (QAM) schemes has been a major challenge in the literature. To address this challenge, this book introduces a novel scalable pipelined VLSI ar- chitecture for a 4 X 4 64-QAM MIMO receiver based on K-Best lattice decoders. The key contribution is a means of expanding/visiting the intermediate nodes of the search tree on-demand, rather than exhaustively along with three types of dis- ...

A novel framework to model the problem of downlink resource allocation in conventional cellular systems and multi-hop cellular networks is presented. In conventional cellular CDMA systems, we use the dynamic pricing platform to formulate downlink resource allocation based on a novel defined cross-layer utility function. This utility function quantifies the degree of utilization of resources. Unlike the previous works, we solve the problem with the general objective of maximizing the total network utility instead of achieved utility of each Base Station (BS). In the second part of the...
