摘要:
Systems and methods for mitigating multipath signals in a receiver are provided. In this regard, a representative system, among others, includes a radio frequency (RF) front-end and at least one analog-to-digital converter (ADC). The RF front-end receives FM signals and down-converts the received frequency signals to intermediate frequency (IF) signals. The analog-to-digital converter (ADC) receives the intermediate frequency signals and digitizes multiple FM channels around a desired FM channel associated with the down-converted signals. The system further includes multiple sets of digital processing components that are configured to simultaneously receive and process the digitized multiple channels. The multiple sets of digital processing components include at least two parallel channel selection and demodulation paths in which the respective digitized multiple channels are processed therethrough.
