摘要：
In this paper Modified Orthogonal Space-Time Block Codes (MO-STBC) were designed as a way to improve the system performance in the presence of "non-quasi-static" fading channels. Loss of orthogonality in symbol decoding is mitigated by a very simple though efficient redesign of the conventional O-STBC encoding scheme. MO-STBC is proven by simulations to significantly outperform the conventional O-STBC despite having exactly the same structure, therefore complexity. Systematic construction of MO-STBC for any number of transmit antennas is also introduced. More over, the combination of MO-STBC with time-selectivity robust decoding techniques is easily implemented yielding improved robustness, also indicated by computer simulations.
