ABSTRACT:
Joint decoding of ISI (Inter-Symbol Interference) channel and modulation codes. A single, combined ISI and modulation decoding module is operable to process a signal received from an ISI communication channel and directly to generate a soft estimate of information encoded therein. A single module employs a decoding transfer function that is substantially matched to the communication channel that introduces the ISI and the modulation encoding performed on the information before being launched into the ISI communication channel. Such operations and functionality are adaptable to a variety of modulation coding systems that are tailored to deal with communication systems that introduce ISI. Moreover, such operations and functionality are extendable to communication systems employing an error correction code (ECC) such as Reed-Solomon (RS) coding as well as ECCs of an iterative nature such as LDPC (Low Density Parity Check) coding, turbo coding, and/or turbo trellis code modulation (TTCM) coding.
