Patent ID: 7324496

Claim:
A method of communicating radio-frequency (RF) signals in a time-division-multiplexed (TDM) communications system using radio-frequency (RF) and signal-processing circuitry in a mobile telephone apparatus, the method comprising: operating the radio-frequency circuitry during a first time period that is a TDM receive slot to generate a set of data that digitally represents in-phase signals and quadrature signals from a radio-frequency signal received by the mobile telephone apparatus; during the first time period, restricting operations performed by the signal processing circuitry on the set of data; storing the set of data in a storage device; operating the signal-processing circuitry during a second time period to process the set of data, the second time period being one of a TDM idle slot and a period during which ramp bits are received; and storing the processed data for use by the mobile telephone apparatus.
