A Maximum Likelihood Decision Based Nonlinear Distortion Compensator for Multi-Carrier Modulated Signals
Summary :
This paper proposes a new nonlinear distortion compensation scheme for orthogonal multi-carrier modulation systems. Multi-carrier modulation is an effective technique for high speed digital transmission over time-dispersive channels, however, it is very sensitive to nonlinear distortion. The proposed scheme compensates for the performance degradation due to nonlinear distortion using the maximum likelihood (ML) detection criterion. While the ideal ML receiver requires a huge computational cost and is not feasible, the proposed decision algorithm can effectively reduce the computational cost. Instead of evaluating the likelihood function for all the possible sequences, the proposed scheme examines the sequences which differ by only one bit from the sequence decoded by the conventional receiver. Computer simulation results show that the proposed scheme can effectively compensate for the nonlinear distortion.
