摘要：

Recently, a new diversity scheme called spatial phase coding (SPC) have been introduced. In conventional SPC, it was assumed that the channel phases between the transmit antennas and the receive antenna independently vary. However, practical channel phase dependently vary between neighboring subcarriers. In this letter, a feedback design method 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.
