Abstract:

An analytical framework is proposed to analyze the effect of feedback error and the closed-form SNR expression is derived. Based on the closed-form expression, the power allocation between the feedback and data transmission stages is given to maximize the achievable rate upper bound. Simulation results show that the achievable rate can be effectively improved by the proposed power allocation and the relay number is limited with noisy limited feedback.

Key words: relay selection, feedback error, power allocation
