Abstract:
1. A system for detecting data in a received signal with data pattern dependent distortion, wherein the data pattern dependent distortion includes intersymbol interference caused by filtering a transmitted signal in a transmitting terminal and a receiving terminal, the system comprising: a distorted signal table configured to store a plurality of known data patterns and samples of distorted signals associated with the known data patterns, the distorted signals including intersymbol interference; a data shift register configured to obtain samples of the received signal within a shifting data pattern window having a length corresponding to a length of the known data patterns; and a detector configured to compare the samples in the data pattern window with the samples in the distorted signal table and to select the known data patterns in the distorted signal table that correspond most closely with the samples in the data pattern window, wherein the detector is configured to output the selected known data patterns as a detected data signal in which intersymbol interference distortion has been mitigated.
