In this paper, inquire a new non-linear precoding method to the acclimatization for the Worldwide interoperability for fixed Microwave Access (WiMAX) baseband, in the physical layer performance of multi-antenna techniques, all cases are based on the IEEE 802.16d standard using Orthogonal Frequency Division Multiplexing (OFDM) based Discrete Wavelet Transform (DWT) and 16-quadrature amplitude modulation (QAM), half of coding rates and using SFF SDR development platform. The proposed non-linear precoding Tomlinson-Harashima Precoding (THP) in WiMAX baseband consider a new way to further reduce the level of interference signals achieved much lower bit error rates and increase spectral efficiency.
