An Adjusted Transmit Power Allocation for the Half-duplex Two-Way Relay Channel Using Analog Network Coding
A half-duplex two-way relay channel system using analog network coding reduces the number of time slots to two,and significantly increases the network capacity,comparing to the traditional routing approach.However,the performance is limited by the propagated noises.In this paper,we analyze the noise propagation,and find that by properly adjusting the nodes transmit power allocation,the achievable sumrate can be enhanced.An adjusted transmit power allocation solution in two-way relay channel using ANC is obtained by comparing to the scheme with uniform transmit power allocation,when the total power is limited.
