Abstract

In this paper, we explore spatial vs. multi-user diversity tradeoffs in terms of outage capacity for a non-homogeneous cellular system with selective feedback. More precisely, we analytically derive an upper bound of the outage capacity of both a SISO and an OSTBC transmission scheme and, further, analyze some interesting trade-offs concerning the impact of terminal count and bandwidth restrictions. Such outage capacity analysis is particulary suited for the study of delay-constrained services. Numerical examples reveal that in many scenarios OSTBC is far less sensitive to impairments in the feedback channel.
