Abstract :
Performance of a parallel symbol transmission scheme is analyzed in time-varying Nakagami fading channels. We show that instantaneous signal-to-interference-plus-noise ratio of the parallel symbol transmission scheme at the matched-filter output is higher than that of a conventional system. Furthermore, the performance gain of the parallel symbol transmission scheme over the conventional system increases as the number of independent fades within the frame increases and/or the Nakagami parameter m decreases.
