INTRODUCTION Multimedia wireless services require reliable high-bit-rate transmission over mobile radio channels. One of the challenges in designing such systems is the mitigation of fading propagation effects within the prescribed bandwidth and power limitations. Multi- ple-input and multiple-output (MIMO) techniques can be implemented to obtain a capacity gain in rich scattering environments without increasing the bandwidth or transmit power and/or to obtain the diversity gain to comba…  相似文献
