Abstract
In this paper, a simplified adaptive modulation (AM) scheme is presented for MIMO spatial multiplexing systems to improve the bit error rate (BER) performance. Constrained to total data rate and equal power allocated to each transmit antenna, an efficient AM algorithm is described to minimize the average BER of the system. The performances of vertical Bell labs layered space-time (V-BLAST) structure combined with the presented AM scheme are investigated. Simulation results have shown that the presented scheme can provide superior performances over the original V-BLAST system under perfect and imperfect channel state information (CSI).
