Distributed Resource Allocation for Downlink Multicell OFDMA Systems

This paper addresses resource allocation for sum throughput maximization in a sectorized two-cell downlink OFDMA systems impaired by multicell interference. It is well known that the optimization problem for this scenario is NPhard and combinational, which is here converted to a novel sum throughput maximization problem based on the intercell interference limitation. Then, two subclasses of thi...

Joint Transmitter-Receiver Optimization in the Downlink CDMA Systems

To maximize the downlink code-division multiple access (CDMA) system capacity, we propose to minimize the total transmitted power of the system subject to users’ signal-to-interference ratio (SIR) requirements via designing optimum transmitter sequences and utilizing linear optimum receivers (minimummean square error (MMSE) receiver). In our work on joint transmitter-receiver design for the dow...

Joint Transmitter-Receiver Optimization for Downlink Multiuser MIMO Communications

This paper develops the joint optimization of linear precoding and decoding for the downlink in multiuser multiple-input multiple-output (MIMO) systems. The system under investigation consists of a single transmitter (base station) with multiple antennas that communicates with several users, each with one or more receive antennas, possibly receiving multiple data streams. The goal is to jointly...
