Abstract

In this paper, we propose P-SRA (Proposed Simplified Resource Allocation) algorithm for efficient resource allocation for real time traffic in MIMO-OFDMA (Multiple Input Multiple Output - Orthogonal Frequency Division Multiple Access) systems with V-BLAST (Vertical-Bell laboratories LAyered Space-Time coding) detector. The proposed P-SRA scheme employs efficient 3 step resource allocation algorithm with plain V-BLAST and no H-ARQ, however it achieves comparable performance of a MIMO-OFDMA system utilizing error compensated V-BLAST and H-ARQ IR scheme.
