【摘要或目录】：This paper analyzes the effects of the level of
cooperation (LOC) on the performance of a practical cooperative
coding scheme for frequency division half-duplex relay links in
general wireless ad-hoc networks. The end-to-end bit error probability
(BEP) and the corresponding optimum LOC minimizing
the end-to-end BEP are investigated for specific realizations using
a family of rate compatible punctured convolutional (RCPC)
codes. This paper shows that the BEP of the cooperative coding
scheme depends on the LOC and there exists an optimum
LOC for every specific realization. Further, it is shown that
more than a certain level of cooperation is required to achieve
possible cooperative gains in practical signal-to-noise ratio (SNR)
regions, and increasing LOC does not effect much on the BEP
performance for sufficiently large LOCs.
