ABSTRACT:
A unique method and apparatus processes and validates Manchester-coded data transmitted on a communications channel and containing a synchronization word and a data word including a plurality of data bits and coded according to a predetermined BCH error correcting code. Each data bit has a binary state determined by a left half non-return-to zero (NRZ) bit sample and a right half NRZ bit sample. The method for processing such data includes the steps of receiving a data word from the communications channel; checking the right half NRZ bit samples of the received data word according to the predetermined error correcting code to detect the number of erroneous bits (810); error correcting the right half NRZ bit samples of the received data word according to the predetermined error correcting code if the number of erroneous bits is less than a first predetermined number (814); comparing the left half NRZ bit samples to the error-corrected right half NRZ bit samples of the received data word to determine the number of data bits that are in error (824); and discarding the received data word if it has more than a second predetermined number of data bits that are in error (830). The novel method may be used in processing data communications in any suitable system, such as, for example, data communications in cellular radio telephone systems.
