Title: Single and Multiple Relay Selection Schemes Download
Description: on relay selection (RS) schemes for
wireless relay networks. First, we derive the diversity of many
single RS schemes in the literature. Then, we generalize the
idea of RS by allowing more than one relay to cooperate.
Several multiple RS schemes are proposed, which are proved to
achieve full diversity. Simulation results show that they perform
much better than the corresponding single RS methods and
very close to the optimal multiple RS scheme. However, the
computational complexity of the suboptimal schemes are linear
in the number of relays, far superior to the optimal selection,
which has exponential complexity. In addition, when the number
of relays is large, the multiple RS schemes require the same
amount of feedback bits from the receiver as single RS schemes.
