Stability condition for PSV: cyclostationary detection

Abstract

the Uses spectral correlation of cyclostationary signals to reduce effect of noise & interference on desire
signal. PSV filter exploits the cyclic frequencies of signal the more different cyclic frequencies the signals have, the more
effective the filter will be. The stability criteria for two-dimensional (2-D) periodically shift variant (PSV) filters,
represented instate space by the first model of FornasiniMarchesini (FM) with periodic coefficients is interesting
challenge. GivoneRoesser Model is an extension for 2-D representation an algorithm with using linear matrix inequality
is proposed to determine the stability of a given 2-D PSV system by sufficient conditions derived for stability analysis.
