Patent ID: 7672266

Claim:
A method of extracting digital data from an analog data signal in a Time Division Multiple Access (TDMA) communications system, the method comprising: exchanging the analog data signal of a communications link in bursts or time slots, wherein the analog data signal is converted to a digital data signal; recovering said digital data by comparing whether said analog data signal is above or below an adaptable threshold or slice level; using a data recovery circuit, wherein said slice level is set for each burst or time slot independently in accordance with specific settings applicable to a communications link associated with a burst or time slot, wherein said data recovery circuit is a digital circuit, and said set slice level is stored for each burst or time slot, adapting said slice level to correct for DC offset experienced by said digital data recovery circuit after receiving a sync word; and comparing said digital data signal and said slice level for providing said recovered digital data, digital filter means being arranged for digitally adjusting filter time constants and said slice level.
