Özet
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.
