Performance of DSTM MIMO systems in continuously changing Rayleigh channel

It is well proved that the signals transmitted through a mutipath channel experience Rayleigh fading. The channel also varies due to the moving of user end or the scatters and Doppler shift effect is generated. Researchers have to consider these two effects in their studies of wireless communications. Some researchers use step channel model which is too idealized to simulate MIMO systems. Besides, sum-of-sinusoid based simulators are widely used among which Jakes' simulator is the most well-known. However this kind of simulator has to strive for the deficiencies in higher-order statistics due to the approximation of random variables by determinants. In this paper, we propose a time selective channel model used for laboratory simulations from a new sight which can avoid the above drawbacks. The channel is reconstructed by sinc function based on Nyquist's sampling theorem. The performance of DSTM scheme is evaluated in this new channel model.
