A novel adaptive receiver for combined channel-estimation and data-detection for digital transmission over time- and frequency-dispersive mobile radio channels

A novel adaptive nonlinear coherent receiver for the detection of M-QAM (or M-PSK) modulated data streams transmitted over randomly time-variant frequency-selective fast-fading macrocellular mobile radio channels is presented. Assuming a TDMA system, the main feature of the receiver is to combine the channel-estimation and the data-detection procedures, thus obtaining enhanced channel-tracking capabilities at nearly the same complexity of conventional adaptive receivers for land mobile data-communication.
