The dynamic decode-and-forward channel: SNR allocation.

Maagh, Stefan; Sharp, John; Binnie, David

Abstract

In the half-duplex relay channel applying the decode-and-forward protocol the relay introduces energy over random time intervals into the channel as observed at the
destination. Consequently, during simulation the average signal power seen at the destination becomes known at run-time only.
Therefore, in order to obtain specific performance measures at the signal-to-noise ratio (SNR) of interest, strategies are required to adjust the noise variance during simulation run-time. It is necessary that these strategies result in the same performance as measured under real-world conditions. This paper introduces three noise power allocation strategies and demonstrates their applicability using numerical and simulation results.
