Equalization is presented as a means to combat the inter-symbol
interference of the frequency-selective fading channel. An introduction to LMS, RLS, and DMI is
given in the context of equalization training and tracking. The performance of space-time equalization
in various channel environments is compared. The eigenspectral decomposition tool is used to
emphasize the relationship between performance improvement and eigenvalues. The equivalence of
the maximum likelihood sequence estimator and various antenna combing methods is provided. As
the wireless systems evolve toward orthogonal frequency-division multiplexing, performing the signal
processing functions in the frequency domain may be more feasible than performing them in the
time domain. It is for this reason that an introduction to frequency-domain equalization is presented.
Also, various symbol (and bit) timing recovery algorithms are provided and performance degradation
due to timing offsets is discussed. Next, various channel quality estimation techniques are compared
and their potential usage scenarios are provided. Lastly, a few frequency correction algorithms are
provided and their performance is discussed.
Chapter 7 provides an in-depth overview of the wideband CDMA (WCDMA) standard covering
topics such as high-speed downlink and uplink packet access.
