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.
