Intersymbol Interference Characteristics of Bandwidth Constrained Communication Channel
S. Naseem Ahmad and Sanjay Kumar Sharma

The paper deals with the problem of the digital wireless communication over band-limited channels most notably telephone channel. The design of adaptive filters for mitigating Intersymbol Interference (ISI) is presented. The performance of adaptive equalizer is studied using computer simulation using ā€œCā€ language under MS-DOS environment. The comparison is made using two communication channels with different step-size and noise variance. The simulation results are included.

Keywords: Intersymbol interference (ISI), band limited channels, minimum mean square error (MMSE), adaptive equalizer.
