A New Scheme to Construct Orthogonal Channel Matrix for MIMO STBC by givens rotation

Journal of Signal and Information Processing 2016年第1期7卷 34-38页

作者： Huanming Zhang Kaiyi Xian Lijun Feng Chaokang Hu Electronics and Information Engineering Institute Foshan University Foshan China

This paper proposes a scheme to construct orthogonal channel matrix for full rate quasiorthogonal STBC based on givens rotation with lower bit error rate. The transmission diversity method rotates every single information symbol. The scheme can suppress channel noise and eliminate the interference term well. Simulation results show that the method can improve performance better than conventional algorithm without increasing decoding complexity.
