Abstract:

An analytical model based on multiple cooperative relays and multiple antennas at the destination in cooperative communication is presented. An approximate method is derived for analysis of the power allocation between the multiple relay nodes and the source node, so the transforming logarithmic operation into linear operation becomes very. Analysis and simulation demonstrate that there exists an optimal power allocation (OPA) parameter when the system model is determined. The effect signal-to-noise ratio (SNR) on the OPA parameter is also shown.

Key words: cooperative communication, virtual multiple-input multiple-output, outage probability, power allocation
