<p>A precoding and decoding system to achieve rates higher than 33.6 kbps in the analog modem to digital modem direction. The system modifies the standard Tomlinson Harashima Precoding algorithm to adapt it for use in PCM modems. Instead of an arithmetic modulo operation that is implemented in the transmitter, the invention defines a Discrete Modulo Operation that performs the function of limiting the amplitude of the transmitted signal.</p> |
