ABSTRACT:
An apparatus and method for detecting signal points transmitted over a transmission line. A data transmitter encodes input data and maps this data in accordance with a Trellis Code Modulation technique. The mapped data is then modulated onto a particular carrier wave, and transmitted to a data receiver. The data receiver compensates for any detected phase shift in the carrier wave, and decodes the phase-corrected data to quickly detect parallel path information of the received data.
