Abstract :
Diversity techniques have been widely used in wireless communication systems because they provide better signal quality in fading channel environments, increasing its capacity. Recently, a new diversity scheme called spatial phase coding (SPC) requiring 1-bit feedback in each subcarrier is introduced. In this paper, a feedback encoder which is more efficient than conventional SPC is proposed. Furthermore, the scheme to improve the BER performance of conventional SPC using 1-bit feedback is suggested.
