The effects of impulse noise on receiving systems are
studied and impulse noise models commonly used in analysis
of such receiving systems are introduced. Various
techniques for identifying the optimum receiving structure
are presented and the concept of a nonlinear receiver
for enhancing receiver
environments is evolved.
performance in impulse noise
The effect of finite predetection
bandwidth on the performance of such nonlinear receiver
structures is studied in a qualitative fashion through
computer simulation. The performance of a linear receiver (matched filter) is
compared to that of nonlinear receiver structures employing
nonlinearities such as blanker and softlimiter;
noncoherent ASK modulation was used for the computer
simulation experiment.
The performance of the blanker and softlimiter is then
compared for different predetection bandwidths. An attempt
was made to optimize a particular receiver structure in
terms of the predetection bandwidth, for a given model
of corrupting noise parameters (Gauss~an and impulsive).
