| Abstract | ||
| In this paper، the approximate expression of pairwise error probability analyzed for distributed convolution code scheme for cooperation communication in wireless network. Moreover، the optimal power allocation analyzed for both cases of error free at relay and error relay case. Also we find optimal power allocation when two relays participate in cooperation instead of single relay. Further، based on the approximate expression of pairwise error probability، the optimum rate allocation is provided for distributed convolution code scheme. Both optimum power and code rate has been studied with considering different triangle channels variation، source-destination، source-relay and relay-destination. Finally، we study the effect of relay selection on optimal power and code rate allocation. | ||
