Abstract | The blind equalization algorithm based on Parzen window method (SQD algorithm) has high computational complexity when systems use high bandwidth-efficiency quardrature amplitude modulation (QAM). A low complexity SQD algorithm (LCSQD) was developed. The judged region of the proposed algorithm was changed from the whole constellation to a circular region of the constellation, whose center was the equalization output and radius could be adjusted experimentally, and which leaded to a low computational requirement. Simulations for 16QAM and 64QAM show that the proposed algorithm has a faster convergence speed than that of SQD algorithm when the residual ISI is the same. |
