| Abstract: | In this paper, we explore spatial vs. multi-user diversity tradeoffs in a cellular system with selective feedback. We first derive closed-form expressions of the average system capacity for both SISO and STBC transmission schemes in order to analytically assess the impact of the number of terminals and bandwidth restrictions in the feedback channel. Next, we analyze several design trade-offs in terms of increased average (long term) system capacity vs. robustness to short-term SNR fluctuations for both transmission schemes under consideration. | ||
