He. Wong et Ja. Chambers, 2-STAGE INTERFERENCE IMMUNE BLIND EQUALIZER WHICH EXPLOITS CYCLOSTATIONARY STATISTICS, Electronics Letters, 32(19), 1996, pp. 1763-1764
Since cyclostationarity is inherent in many man-made signals, there is
much to be gained in the signal processing and communication areas if
this property is properly recognised and exploited. In particular, th
e authors propose a novel two-stage scheme which exploits second-order
cyclostationary statistics for co-channel interference removal and bl
ind equalisation. The first stage adopts the blind adaptive (BA) FRESH
filter proposed by Zhang, to remove co-channel interference and chann
el noise. The second stage is based on a blind equalisation algorithm,
proposed by Tong, which operates on the filtered cyclic signal to rem
ove intersymbol interference. Simulation studies have demonstrated tha
t this two-stage blind equalisation scheme has a fast rate of converge
nce and excellent performance in a high SNR environment.
