Abstract :
Both transmit and receive diversities are employed to establish independent wireless channels in the same bandwidth and the same time for increasing the spectrum efficiency between two localized transceivers. We study five approaches to determine the antenna weights. Among them, a novel SVD-MMSE approach is proven to achieve the best system performance
