Abstract :
In the conventional Space-Time Block Code (STBC) scheme, system can´t achieve the full diversity and full rate for more than two transmitting antennas. Thereafter, a Quasi-Orthogonal STBC (QOSTBC) has been provided to improve the diversity and full rate behavior for the STBC with more than two transmitting antennas. However, QOSTBC has the drawback of heavy computational burden for the receiver. This paper proposes a simple QOSTBC transmission scheme with the low computational complexity. Besides, we will demonstrate that the proposed method has almost the same Bit Error Rate (BER) performance compared with the Rotated QOSTBC (RQOSTBC) decoder.
