Résumé:
Widely linear (WL) receivers are able to fulfill single
antenna interference cancellation (SAIC) of one rectilinear (R) or
quasi-rectilinear (QR) co-channel interference (CCI). The SAIC
technology for QR signals is operational in GSM handsets but has
been shown recently to be less powerful than SAIC for R signals.
To overcome this limitation, a SAIC/MAIC enhancement based
on the concept of three inputs WL frequency-shift (FRESH)
receiver has been introduced recently for QR signals. However,
this new receiver loses its efficiency for an interference having a
residual frequency offset (FO) above a small fraction of the baud
rate. It may be the case for airborne communications, due to high
differential Doppler shifts, and it is the case for the inter-carrier
interference (ICI) of filter-bank based multicarrier (FBMC)
waveforms using OQAM constellations, which are candidate for
5G mobile networks. In this context, the first purpose of this
paper is to extend both the standard two-inputs SAIC/MAIC
receiver and the concept of three inputs WL FRESH receiver
for QR signals with FO. The second purpose is to analyse both
analytically and by simulations the impact of this FO on the
performance of these receivers
