Layer-encoded multimedia multicasting (LMM) has emerged in recent years to support heterogeneous subscriber stations with diverse computing and networking capabilities. With the advance of broadband wireless access technologies, wireless relay networks (WRNs) are expected to provide significant improvement on throughput and extension of coverage for next-generation wireless systems. In this paper,...
The problem of how to optimally allocate available resources (e.g., bandwidth and power) in OFDM-based multicast wireless systems is important. Taking the maximization of system throughput as the design objective, an efficient resource allocation scheme is proposed for such systems under constraints on total system bandwidth and transmit power at the base station. Different from existing methods in...
