Description: This contribution considers semi-blind adaptive equalization for communication systems that employ high-throughput quadrature
amplitude modulation signalling. A minimum number of training symbols, approximately equal to the dimension
of the equalizer, are first utilized to provide a rough initial least-squares estimate of the equalizer’s weight vector. A
novel gradient-Newton concurrent constant modulus algorithm and soft decision-directed scheme are then applied to adapt
the equalizer. The proposed semi-blind adaptive algorithm is capable of converging fast and accurately to the optimal
minimum mean-square error equalization solution. Simulation results obtained demonstrate that the convergence speed of this
semi-blind adaptive algorithm is close to that of the training-based recursive least-square algorithm

Description: A semi blind technique for estimating the carrier frequency offset in OFDM communication systems is presented in this
paper. The fractional and integer frequency offsets are esti-mated by employing a few null subcarriers in the rst OFDM
symbol in a frame. While the conventional null subcarrier based methods estimate the offset by a single global search, the
proposed method employs a two stage estimator, which greatly minimize the computational complexity. ,A semi blind technique for estimating the carrier frequency offset in OFDM communication systems is presented in this

in ultra-wideband communications due to the short duration

based on maximum-likelihood techniques to recover both symbol

Description: There is a trend to develop blind or semi-blind source extraction algorithms based on
second-order statistics, due to its low computation load and fast processing speed.
An important and primary work is done by Barros and Cichocki, who propose an
extraction algorithm based on a time delay. The algorithm is simple and fast, but its
performance is not satisfying. The paper extends their work and proposes a robust
algorithm based on eigenvalue decomposition of several delayed covariance matrices.
It is faster and has better performance, which is conˉrmed by theoretical analysis
and computer simulations.
