Space-time blind decision feedback equalizer
João Mendes Filho, Magno T. M. Silva, María Dolores Martínez Miranda · 2006
We address the problem of signal separation using space-time blind decision feedback equalizer. Assuming correct decisions and absence of noise, the perfect equalization conditions are obtained. We present an extension of the blind algorithm which avoids degenerated solutions in the single-input single output case. The proposed algorithm jointly adapts the feedforward and feedback filters of DFE, avoids degenerated solutions, and has capability of simultaneously recovering all sources.
