  • To improve the porformance of Space-Time Block Code (STBC) over time-selective fading channels, the Coordinate Interleaved Space-Time Block Code (CISTBC) is proposed. Compared with the existing STBC, CISTBC sends the real and imaginary parts of each symbol from different antennas. This makes the best of the multi-path transmission resulted from the time-varing character of the channel coefficients and strengthens each symbols resistance to the deep fading. Moreover, from QR decompostion and gaussian approximation (GA), the impact of successive interference cancellation (SIC) algorithm on different symbols decoding performnance is analyzed. A Circular SIC (CSIC) algorithm to combat the error propagation and obtain an extra performance gain is developed. Analysis and simulations demonstrate that CISTBC can effectively improve the performance of STBC over time-selective fading channels.
