Apparatus and method for utilizing a blind equalizer based on a Bayesian symbol sequence estimator for use in digital communication

(once amended) An apparatus for performing blind equalization of digital communication over a communication channel upon which data signals are received comprising:

• a memory for storing every possible data subsequence in which intersymbol interference could occur and for storing updated communication channel coefficients;
• a first data bus coupled to said memory for communicating said received data signals, stored data subsequences and stored updated communication channel coefficients;
• a plurality of signal processors each coupled in parallel to said first data bus, each processor for generating estimated received data signals and updated estimated communication channel coefficients, each processor generating said estimated received data signals and updated estimated communication channel coefficients for one of said stored possible data subsequences;
• a second data bus coupled in parallel to said plurality of signal processors for communicating said estimated data signals and updated estimated communication channel coefficients;
• and
• a central processing circuit coupled to said first and second data buses for controlling operation of said first and second data buses and said plurality of signal processors, for estimating unconditional channel coefficients, for storing said estimated unconditional channel coefficients in said memory, and for decoding said received data according to a Bayesian estimation based on said estimated unconditional channel coefficients and updated estimated communication channel coefficients for each of said stored possible subsequences,
• whereby said received data which is subject to data smearing is reliably decoded notwithstanding intersymbol interference and without use of training data or signaling preambles.
