Abstract :
A novel polarization receiver for suppressing narrowband interference (NBI) in ultra-wideband (UWB) communication systems is proposed. A null phase-shift polarization (NPSP) filter, consisting of linear polarization vector transformation (PVT), conventional single notch polarization (SNP) filtering, and amplitude and phase compensation (APC), is utilized. The NBI, which has polarized states different from those of the UWB, can be suppressed completely and the UWB signal can be recovered without distortion. Analytical and simulation results indicate that the signal-to-interference ratio and BER performance can be improved effectively after NPSP filtering. The proposed receiver can be implemented in a time-hopping spread spectrum (TH-SS) or a direct-sequence spread spectrum (DS-SS) UWB system.
