Abstract

For a three-node amplify-and-forward (AF) two-way relay network (TWRN), we investigate the power allocation problem during the channel training process for both terminals to estimate the global channel state information (CSI) of the whole network. This includes the power allocations between different training steps and among different nodes. Two power allocation schemes are proposed: a mean-square-error (MSE) based scheme and an outage probability (OP) based scheme. Our simulation results demonstrate that the proposed power allocations are superior to even power allocation.
