Abstract

In this paper, new space time/frequency block coding (STBC/SFBC) scheme with angle feedback for 4-transmit antennas is proposed. This scheme achieves the full diversity gain with the full code rate by rotating constellation symbols in STBC/SFBC codewords using the quasi-orthogonal structure. With multiple receive antennas, this scheme can also be applied with additional receive antenna diversity. We show the channel characteristics can be much improved with as small as 1-bit feedback overhead. Simulation shows that the proposed scheme with 1-bit feedback achieves near-optimum performance.
