Abstract

DBN (Deep Boltzman Net) algorithm is proposed to cancel for the variable frequency offset (FO) in orthogonal frequency division multiplexing (OFDM) system. The DBN network is composed of two stages including w(k) scheme and H(k) scheme. W(k) is selected to pre-cancel the variable frequency offset firstly, and then the residual interference has been cancelled by the H(k) scheme. Bit error rate is simulated to demonstrate the proposed method is robust for canceling the variable frequency offset.
