The nonlinear equalizers are based on minimum bit error rate (MBER) algorithm. Out-band interference caused by nonlinear distortion is suppressed by digital pre-distorters, and in-band distortion is reduced by nonlinear equalizers. Simulations show that the performance of nonlinear equalizers based on MBER is superior to that based on minimum mean square error algorithm. Through joint compensation of pre-distortion and equalization, the digital distorters can be simplified and the performance of bit error rate can be improved. %U https://journal.bupt.edu.cn/EN/10.13190/j.jbupt.2016.06.007
