Link Budget Improvement of Cooperative Diversity with WCDMA Method Implementation

Giorgi Tabuashvili

Abstract—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 work, we calculate the link budget and cell radios for cooperative communication with WCDMA access method and mini TDMA scenario between mobiles. Calculation is done for urban, medium and residential areas based on computer simulation. Two propagation models: Motorola Xlos and Ericsson indoor propagation models are used for this. The link budget calculation and simulation results show the advantage of cooperative communication, which prolongs cell radius and improves receiver sensitivity.

Index Terms—Cooperative communication, link budget, propagation model, WCDMA access method.
