ABSTRACT:
Increased numbers of multipath transmission errors, that are detected by the performance of cyclic redundancy checking (CRC) over time and frequency on the words of a multitone transmission block that include mapped information bits, are correctable by forward error control as a result of the iterative performance of CRC over frequency on subblocks of the transmission block using retransmitted parity checking bits. A continuous record is maintained of the frequency channels that are detected as experiencing transmission errors in order to maximize the rate of data bit transmission on frequency channels that are likely to experience a reduced number of transmission errors.
