Executive Summary

Cooperative transmission has been of growing interest recently where users take advantage of each other's resources for better overall performance. User cooperation provides uplink transmit diversity even when mobile units cannot accommodate multiple antennas due to size constraints. Recently, a versatile user cooperation method called coded cooperation diversity was introduced by many researchers, in which a variety of channel coding methods are used to implement cooperation. Different radio access methods could be used for this implementation. In this paper, the authors calculate the link budget and cell radios for cooperative communication with WCDMA access method and mini TDMA scenario between mobiles.
