摘要： A method of activating a radiotelephone operable in a spread-spectrum multiple access radiotelephone system. A searcher receiver (114) is activated, and the searcher receiver (114) acquires a PN sequence timing of a pilot signal. At least one demodulation branch (122) is activated after activation of the searcher receiver (114), and the demodulation branch synchronizes to the PN sequence timing of the selected pilot signal after the searcher receiver (114) has acquired the PN sequence timing.

摘要： An apparatus and method is disclosed to calculate the actual received desired channel power from the downstream transmit power of a Cable Modem Termination System (CMTS) when operating at the nominal line voltage and/or at the normal room temperature as per the DOCSIS specification. A Set-top Device produces a Downstream Power Management (DPM) gain measurement signal having a known power level. The Set-top Device embeds the DPM gain measurement signal onto a received downstream multi-channel communication signal. After embedding the DPM gain measurement signal onto the downstream multi-channel communication signal, the Set-top Device downconverts the combined DPM gain measurement signal and downstream multi-channel communication signal to recover one or more communication channels containing information of a broadcast. The Set-top Device measures a power level of a representation of the DPM gain measurement signal embedded within the one or more communication channels containing the information of the broadcast to determine a Set-top Device gain. The Set-top Device measures a power level of the one or more communication channels containing the information of the broadcast. The Set-top Device calculates the actual received desired channel power from the downstream transmit power of the CMTS based on the Set-top Device gain and the power level of the one or more communication channels containing the information of the broadcast.

摘要： An apparatus for acquiring a pseudo-random (PN) sequence timing for a code division multiple access (CDMA) radiotelephone. A buffer stores samples of representations of at least one pilot signal. A correlator coupled to the buffer is operable to correlate at least a portion of the samples with a PN sequence at each of a plurality of different PN offsets to produce corresponding correlation energies. A controller coupled to the correlator interrupts the correlator as soon as the PN sequence at a particular PN offset produces a correlation energy at least equal to an energy threshold.
