Abstract:
A RF receiver that comprises: (i) a complex mixer for converting a version of the RF signal to a complex baseband signal comprising an in-phase component and a quadrature component; (ii) one or more analog-to-digital converters (ADCs) connected to the complex mixer for digitizing the in-phase component and the quadrature component of the complex baseband signal; and (iii) a digital signal processor (DSP) connected the one or more ADCs. The DSP is programmed to mitigate interference in the complex baseband signal by a process that comprises the steps of: (i) performing at least one cross correlation operation involving L-length segments of the digitized in-phase and quadrature components of the complex baseband signal; and (ii) concatenating the cross-correlated L-length segments of the digitized in-phase and quadrature components of the complex baseband signal to produce digitized interference mitigated in-phase and quadrature components of the complex baseband signal.
