Digital compensation of the power amplifier nonlinearities at relay station receivers in 802.16j very high data rate systems

In this paper, a digital algorithm is proposed for the compensation of base station power amplifier nonlinearity for 802.16j very high data rate systems. The compensation takes place into the relay station receiver, which reduce the overall network power consumption. Simulation results show good performance enhancement, while an experimental test bed achieves the proof of concept on WIMAX signal.
