PR-QMF based decision feedback equalization
Shi Qing · Journal of China Institute of Communications · 2001
Based on PR QMF theory,we construct a class of orthogonal transforms and apply them to the design of transform domain decision feedback equalization Then we further investigate the optimization design of these DFEs Compared with Karhunen Loeve Transform(KLT)and Discrete Cosine Transform(DCT),we attain the following conclusions:the proposed scheme together with the optimization design can provide better convergence performance In addition,it has the advantages of low complexity and adaptability for different channels
