ABSTRACT: The conventional orthogonal space-time block code (OSTBC) with limited feedback has fixed p-1feedback bits for the specific ntptransmit antennas. A new partial feedback based OSTBC which provides flexible feedback bits is proposed in this paper. The proposed scheme inherits the properties of having a simple decoder and the full diversity of OSTBC, moreover, preserves full data rate. Simulation results show that forntp transmit antennas, the proposed scheme has the similar performance with the conventional one by using p-1feedback bits, whereas has the better performance with more feedback bits.
