Patent ID: 7627062

Claim:
A method for equalization of a signal which is transmitted via a useful channel using a decision feedback (DF) method and taking into consideration at least one disturbance channel, per unit time comprising: (a) processing, by a processor, a trellis diagram of the useful channel; (b) processing, by the processor, a trellis diagram of the disturbance channel, with a DF contribution which is used in the processing of the trellis diagram of the disturbance channel containing information, determined in step (a), of the useful channel; (c) processing, by the processor, the trellis diagram of the useful channel being once again, with a DF contribution, which was used when the trellis diagram of the useful channel was processed once again, containing information, determined in step (b), of the disturbance channel; and wherein input information being accessed in step (a) during the processing of the trellis diagram of the useful channel, which input information was determined when the trellis diagram of the useful channel was processed once again in step (c) in a previous time unit.
