Data-aided channel estimation based on maximum-likelihood criterion has recently been proposed for ultra-wideband communications. However, its perform...

Motivated by the recently proven theorem about the statistical properties of nonlinearly distorted phase-shift keyed (PSK) signals, we show that the t...

The linearly constrained constant modulus algorithm (LCCMA) applied to blind DS-CDMA multiuser detection was widely considered in the last few years....

Walsh filtering has been used as a method to reduce receiver complexity in several coding and modulation systems, especially in continuous phase modul...

An adaptive blind multiuser detection algorithm is proposed for asynchronous direct-sequence code-division multiple-access (DS-CDMA) systems based on...
