Blind Signal Processing Technology In Channel Equalization
Wen Wang · Communications technology · 2008
In high-speed transmission,due to coupling effect and multi-address disturbance,signals disturbance occurs and reduces the speed of data signal transmission.Channel equalization technology is used to eliminate the signal disturbance and repay the channels,thus to improving the communication quality while reducing signal error rate.Channel equalization technology includes two aspects:adaptive equalization and blind channel equalization1.Due to the former’s disadvantages,the latter emerges and has attracted more and more attention for its advantages.In this paper,the author tells of the occurrence of signal disturbance and the mathematic basis of blind channel equalization,and discusses several calculation methods of blind channel equalization.
