摘要：A wireless communication network comprising a wireless receiver. The wirelessreceiver comprises at least a first antenna for receiving packets, wherein each of thereceived packets comprises a plurality of bits and each of the plurality of bits ismodulated by a frequency offset. The wireless receiver also comprises circuitry forcycling through a hopping sequence, wherein the hopping sequence comprises asequence of frequency bands and circuitry for demodulating each received packet inresponse to a frequency band in the hopping sequence. The wireless receiver alsocomprises circuitry for detecting the frequency offset of each of the plurality of bits andconverting the frequency offset of each of the plurality of bits into a corresponding DCvoltage for each of the plurality of bits. Still further, the wireless receiver comprisescircuitry for sampling the DC voltage for each of the plurality of bits and providing a DCoffset voltage for each of the plurality of bits, and it also comprises circuitry for providinga filtered DC offset voltage by filtering the DC offset voltage. Lastly, the wireless receiveralso comprises circuitry for providing a digital value corresponding to each of theplurality of bits in response to the corresponding DC voltage for each of the plurality ofbits as adjusted in response to the filtered DC offset voltage.
