For joint maximum-likelihood (ML) frequency tracking and channel estimation using orthogonal frequency-division multiplexing (OFDM) training blocks in OFDM communications over mobile wireless channels, a major difficulty is the local extrema or multi

For digital data transmission using an orthogonal frequency-division multiplexing (OFDM) over fading channels, the interchannel- interference (ICI) term caused by the Doppler spread is correlated with the desired signal term. Nonetheless, many resear

Based on the expression of the error probability for the infinite length equalizer and the error bound for the finite length equalizer for M-ary PAM channels using the unbiased decision rule, we are inspired to develop an adaptive algorithm called th

By using a ‘pre-averaging method’, we successfully derive an exact closed-form symbol error rate (SER) expression for the particular case of two transmit-one receive antenna diversity system employing arbitrary rectangular M-QAM signalling over f

We propose new adaptive minimum symbol error rate algorithms (MSER) for decision feedback equalization over M‐ary PAM channels. In addition, we take into consideration biased as well as unbiased estimates leading to two major versions respectively

In this work, the effect of changing symbol rate (or equivalently, symbol rate) on the equalizer performance for M-ary PAM systems is investigated. We keep increasing the symbol rate (or equivalently, keep decreasing the symbol period) until a limit
