Among various techniques concerning MIMO system capabilities, Linear Dispersion Codes (LDC) conquer many deficiencies of earlier proposed schemes and achieve both the coding advantage and decoding simplicity. However, since no specific criterion is proposed to determine the coding length of LDC, the optimization of the symbol rate, which will essentially influence the system efficiency, is impossible. This paper studies the effect of these two key parameters on the LDC systems and puts forward a practical parameter decision and optimization criterion to lessen the coding complexity while retaining the codes' near-optimum performance simultaneously. Simulation results yield the trivial capacity loss and excellent BER over a wide range of SNR situations.
