This is the second in a two-part series of papers on
a new form of spatial diversity, where diversity gains are achieved
through the cooperation of mobile users. Part I described the
user cooperation concept and proposed a cooperation strategy
for a conventional code-division multiple-access (CDMA) system.
Part II investigates the cooperation concept further and considers
practical issues related to its implementation. In particular, we investigate
the optimal and suboptimal receiver design, and present
performance analysis for the conventional CDMA implementation
proposed in Part I. We also consider a high-rate CDMA implementation
and a cooperation strategy when assumptions about
the channel state information at the transmitters are relaxed.
We illustrate that, under all scenarios studied, cooperation is
beneficial in terms of increasing system throughput and cell
coverage, as well as decreasing sensitivity to channel variations.
