COOPERATIVE MULTIPLE ACCESS BROADCAST TRANSMISSION STRATEGY AND PERFORMANCE ANALYSIS IN ASYMMETRIC TWO-WAY RELAY SYSTEM

Cooperative multiple access broadcast transmission strategy and performance analysis in asymmetric two-way relay system

In a two-way relay system where two nodes exchange information via a half-duplex relay,the achievable data rates of both directions are limited by the weaker link.When the two-way channel is asymmetric due to relay positioning or channel fading,the sum rate of the two-way relay system will suffer from severe degradation.In order to compensate for t
