Jin-Nan Li · Frequenz · 1995
Carrier phase recovery in Maximum Kurtosis Deconvolution (MKD) based blind equalization are investigated. The sensitivity of the MKD based equalization algorithm to carrier frequency offset is discussed. Structures for combined MKD based equalization and carrier phase tracking are proposed. A new algorithm that is based on the kurtosis of the real part of the equalizer output is also introduced. The algorithm may simultaneously equalize the channel and recover the carrier phase. A rigorous analysis shows that the performance of the new algorithm is superior to the other MKD based blind equalizers. It is also demonstrated, by means of extensive simulation that the new algorithm performs very well and outperforms the other MKD based algorithms.
