Abstract: There is provided a scheme for centering data prior to detection. It is characterized by: determining carrier frequency error, and pre-adjusting (G1) the data detection process to compensate for that error throughout the ensuing data detection. This scheme for reliable multi-level data detection is further characterized by: upon detection of carrier presence, determining carrier frequency error, gating (G1) a voltage associated with the frequency error (C1) to the differential amplification process (DIFF) to establish common mode rejection and compensating for that error (C1) throughout the ensuing multi-level data detection, and then analog-to-digital conversion (A/D) of the differentially amplified multi-level data. A scheme for computationally centering the subsequent data detected to compensate for the error is also provided.

Abstract: 2055470 9014727 PCTABS00002 There is provided a scheme for centering data prior to detection. It comprises: determining carrier frequency error, and pre-adjusting the data detection process to compensate for that error throughout the ensuing data detection. This scheme for reliable multilevel data detection further comprises: upon detection of carrier (C2, R5, G1) presence, determining carrier frequency error, gating a voltage associated with the frequency error (R1, R3, C1) to the differential amplification process to establish common mode rejection and compensating for that error throughout the ensuing multi-level data detection, and then analog-to-digital conversion of the differentially amplified multi-level data. A scheme for computationally centering the subsequent data detected (C3, R4) to compensate for the error is also provided.

Abstract: A communications system having a plurality of different radio-types (528, 530 and 532) when integrated into a single node or control module (500) provides communications with a plurality of different end users (502, 506 and 508) having different transmission protocols. The steps involved comprise coupling the plurality of communication devices (528, 530 and 532) together via a bus (526) and coupling at least one processing unit (517) to the bus (526). Signals received by RF devices (528, 530 and 532) are communicated onto the bus (526) and processed by the processing unit (517) into processed signals. Processed signals comprise data and control information which are stored in memory (522). Thereafter, the processed signals stored in memory (522) are returned back onto the bus (526) for use by at least one of the plurality of communication devices (528, 530 and 532).
