摘要：

High data rate space time/frequency block coding (STBC/SFBC) suffers from interference due to its non-orthogonal structure of the effective channel. This paper presents new STBC/SFBC scheme to suppress interference with an aid of angle feedback. The proposed scheme achieves the full diversity gain with the spatial code rate of two by rotating constellation symbols in STBC/SFBC codewords. We find the closed form solution for the feedback angle and propose 1-bit feedback criterion. Simulation shows that the proposed scheme with 1-bit feedback improves the system performance significantly.
