SAIC pour une interférence circulaire au second-ordre par filtrage de Volterra complexe d'ordre 3

Abstract : It has been recently proved that in the presence of a rectilinear signal of interest (SOI) and a co-channel interference (CCI), received on a single antenna, the rejection of a strong interference can be greatly improved by the use of a MMSE third-order complex Volterra filter in place of a MMSE widely linear filter (WL). This improvement is achieved by exploiting both the non-Gaussiannity and the non-circularity of the signals up to the 6th-order, rather than the second-order non-circularity exploited by the WL filters. This makes it possible, at least for BPSK signals, the exploitation of the amplitude discrimination in addition to the phase discrimination between the signals. The aim of this contribution is to examine whether these properties remain valid for second-order circular signals, ubiquitous in radiocommunications
