Non-data-aided ML carrier frequency and phase synchronization in OFDM systems
(Wiley-Blackwell, 2001-04)
In this paper non-data-aided(NDA), maximum likelihood(ML) algorithms are derived for the carrier frequency and phase offset, separately, for OFDM systems employing M-PSK modulation scheme. NDA ML estimation algorithm for ...
On the performance of trellis coded M-PSK systems over Rician fading channels with phase jitter
(Assoc Elettrotecnica Ed Elettronica Italiana, 2001-02)
In this paper, the performance of trellis coded M-PSK systems is investigated operating over Rician fading channels with phase jitter. Thus the results reflect not only the degradation due to the effect of fading on the ...
Design and performance analysis of a novel trellis coded space-time-frequency OFDM transmission scheme
(Wiley-Blackwell, 2008-01)
In this paper a new transmit diversity technique is proposed for wireless communications over frequency selective fading channels. The proposed technique utilises orthogonal frequency division multiplexing (OFDM) to transform ...
Design of optimum nyquist signals based on generalized sampling theory for data communications
(IEEE, Piscataway, NJ, United States, 1999-06)
A new method is given for the optimal design of bandlimited Nyquist-type signal shapes for data communications, which maximizes its energy in a given time interval. The method is based on the periodically nonuniform sampling ...
Adaptive Volterra channel equalisation with lattice orthogonalisation
(Institution of Engineering and Technology, 1998-04)
The authors present a new recursive least-squares adaptive nonlinear equaliser based on Volterra series expansion. The main approach is to transform the nonlinear equalisation problem into an equivalent multichannel, but ...
A low-complexity KL expansion-based channel estimator for OFDM systems
(Springer International Publishing, 2005-04-05)
This paper first proposes a computationally efficient, pilot-aided linear minimum mean square error (MMSE) batch channel estimation algorithm for OFDM systems in unknown wireless fading channels. The proposed approach ...
