SPACE-TIME LINEAR DISPERSION CODES BASED ON OPTIMAL ALGORITHMS
Multiple-antenna systems that operate at high rates require simple yet effective space-time transmission schemes. Lin-ear dispersion (LD) codes transmits substreams of data in linear combinations over space and time. The traditionally LD codes are mainly designed to optimize the mutual information which cannot guarantee good error performance. In contrast, using the simulation-based optimization method can minimize the block error rate (BLER), but failed to optimize the channel capacity to the fullest extent. In this paper, a new design algorithm will be presented which would achieve both lower BLER and higher capacity by adding some extra quali-fications in the simulation process. Simulation results show that the proposed method has a better performance over a large range of SNRs than the earlier proposed methods.
