Stochastic Gradient Adaptive Minimum Symbol-Error-Rate Equalization for Multi-Level Pulse-Amplitude Modulation

Recursive Least Squares Adaptive Filter a better ISI Compensator

Inter-symbol interference if not taken care off may cause severe error at the receiver and the detection of signal becomes difficult. An adaptive equalizer employing Recursive Least Squares algorithm can be a good compensation for the ISI problem. In this paper performance of communication link in presence of Least Mean Square and Recursive Least Squares equalizer algorithm is analyzed. A Model...

A wide-band radial basis function decision feedback equalizer-assisted burst-by-burst adaptive modem

The performance of radial basis function-based decision feedback equalized (RBF DFE) burst-by-burst adaptive quadrature amplitude modulation (AQAM) is presented for transmissions over dispersive wide-band mobile channels. This scheme is shown to give a significant improvement in terms of the mean bit error rate (BER) and bits per symbol (BPS) performance compared to that of the individual fixed...

Adaptive Beamforming Assisted Receiver

Adaptive beamforming is capable of separating user signals transmitted on the same carrier frequency, and thus provides a practical means of supporting multiusers in a space-division multipleaccess scenario. Moreover, for the sake of further improving the achievable bandwidth efficiency, highthroughput quadrature amplitude modulation (QAM) schemes have becomes popular in numerous wireless netwo...
