Abstract :
This paper presents a new spatial division multiplexing (SDM) based scheme combined with space time block coding (STBC) for cyclic prefix based single carrier block transmission (CP-SCBT). CP-SCBT technique converts the linear convolution of the frequency selective fading channel to the circular convolution. The optimum detection scheme based on the minimum mean square errors (MMSE) criterion can be easily solved with FFT/IFFT after simple pre-processing in the receiver. The bit error ratio (BER) performances over different channels are assessed by simulations.
