New Blind Equalizer Based on Filtering in DCT Domain
Jiashu Zhang · Journal of Southwest Jiaotong University · 2003
Based on the constant modular algorithm (CMA), a new type of blind equalizer wit h filtering in discrete cosine transformation (DCT) domain is proposed for the amplitude- and phase-modulated digital communication systems. Computer simulat ions show that the performance of the proposed blind equalizer is superior to th at of the CMA equalizer.
