| Abstract: | Channel equalization is an essential technology for wireless communication to improve channel performance and reduce the ISI.Based on the analysis on the DDLMS algorithm,the application of this algorithm in channel equalizer is studied.MATLAB is used to simulate the algorithm.A Channel Equalizer based on DDLMS algorithm is implemented with a development software Xilinx System Generator for DSP.The simulation test results show the equalizer can eliminate ISI. |
