Abstract

We present a new transmit strategy based on modified Alamouti codes for the simple two branch transmit diversity scheme. The OFDM payload cells from the output of the frequency interleaver is done on one transmit antenna, and the encoding is proceeded on another branch. The proposed encoding scheme can significantly simplify the processes of transforming SISO into MIMO in wireless communication systems. The scheme may easily be generalized to two transmit antennas and M receive antennas to provide a diversity order of 2M, its coding gain is similar to Alamouti code. Computer simulations are performed to investigate the performance of the proposed parallel STBC scheme in a multi-input (MI)system.
