Abstract
A pre-coder is designed for orthogonal space-time block codes (OSTBCs) in multiple-input multiple-output (MIMO) channels. Unlike previous works, our pre-coder is the first to be designed to minimize the exact symbol error rate. In this paper, we show that OSTBCs can achieve full diversity and nearly strict orthogonality with a small amount of feedback bits returned from the receiver back to the transmitter. Along with pre-coding of the OSTBC, also the proper utilization of partial CSI is done at the transmitter side to improve overall characteristics of the system. Simulation results of the pre-coding OSTBC is discussed along with its antenna design technique.
