摘要： Techniques for detecting jammers in a received signal are described. A jammer detector includes a jammer filter for attenuating transmit signals leaked into the receive path, a pulse generator for converting the interference signals into discrete-level pulses, and a pulse processor for determining the presence of jammers in the discrete-level pulses. In an exemplary embodiment, the pulse processor is configured to further discriminate among close-in jammers that are close to the desired receive frequency, far-away jammers, and jammers arising from the transmit signals leaked into the receive path. In another exemplary embodiment, hysteresis is provided in the pulse generator to enable the generation of reliable pulses. Further aspects include configuring the jammer detector for operation in a plurality of frequency bands and/or according to a plurality of communications standards.
