Maximum likelihood blind channel estimation for space-time coding systems
(Hindawi Publishing Corporation, 2002-05)
Sophisticated signal processing techniques have to be developed for capacity enhancement of future wireless communication systems, In recent years, space-time coding is proposed to provide significant capacity gains over ...
Iterative channel estimation approach for space-time/frequency coded OFDM systems with transmitter diversity
(Assoc Elettrotecnica Ed Elettronica Italiana, 2004-06)
Focusing on transmit diversity orthogonal frequency division multiplexing (OFDM) transmission through frequency selective channels, this paper pursues novel iterative channel estimation approaches for both space-frequency ...
Adaptive Kalman receiver for OFDM systems with transmit diversity in mobile wireless channels
(Walter De Gruyter GMBH, 2004-12)
A new joint channel tracking and symbol detection scheme is proposed in this paper for pilot symbol assisted transmit diversity OFDM systems by exploiting the correlation of the adjacent subchannels. Modelling the channel ...
Analysis of self-noise in a clock recovery system with a high-order nonlinearity
(IEEE-INST Electrical Electronics Engineers Inc, 2003-11)
This correspondence presents a new technique to compute efficiently the spectra of the in-phase (I) and quadrature (Q) components as well as the cross-spectrum of the in-phase and quadrature (I-Q) components of self-noise ...
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 ...
