Full and partial frequency reuses for the layered bitstream transmission

Abstract

This paper addresses the optimal frequency reuse for the transmission of multimedia layered source which needs unequal target error rates or spectral efficiencies in its bitstream. We first analyze the crossover point of the outage probability curves for the full and partial frequency reuses, and show that that the crossover point in signal-to-noise ratio is a strictly increasing function in spectral efficiency. Based on the analysis, we propose the employment of the unequal frequency reuses for the transmission of a sequence of multimedia scalable packets.
