Abstract. Equalization techniques are commonly used
in low to moderate data transmission over time varying wireless mobile
channels. Their use is mainly to alleviate the detrimental effect of
intersymbol interference brought about by the multipath phenomena of such channels.
The wireless multipath channel is time varying which makes the use of adaptive
equalization a necessity to cope with channel variations and consequently to
overcome resulting intersymbol interference effects, restore the transmitted
symbols, and extract the information being sent. The first part of this paper
presents a comparison study of the performances of four representative methods
of adaptive equalization. Linear and nonlinear structures each with both LMS
and RLS adaptation algorithms are used in the investigation. In the second part
of the paper, a computer simulation is carried out to investigate the
relationship between the number of propagation paths of the wireless mobile
channel and the number of taps in the incorporated adaptive equalizer. Four
equalizer structures are used in this investigation which is based on Simulink
software package to simulate a communication system incorporating these
equalizers. The bit error rate (BER) performance is used as a measure for
establishing this dependency.
