Abstract
Systems for recovering communicated information in a communication system are disclosed and may include at least one digitizer for digitizing an analog received signal comprising the communicated information, thereby creating a digital received signal. The system may include at least one filter for bandwidth-limiting at least a portion of the digital received signal. At least one feed forward equalizer may be used for equalizing at least a portion of the bandwidth-limited signal to create an equalized signal. At least one converter for creating a data signal according to at least the equalized signal. At least one soft decision circuit for creating a soft decision signal according to the data signal. The soft decision circuit may cancel at least a portion of the equalized signal.

79. A system for recovering communicated information in a communication system, the system comprising:
-
at least a first digitizer and a second digitizer for digitizing an analog received signal comprising the communicated information, thereby creating a first digital received signal and a second digital received signal; at least two filters, wherein a first filter receives and filters said first digital received signal and a second filter receives and filters said second digital received signal; at least two feed forward equalizers, wherein a first feed forward equalizer equalizes the first filtered signal and a second feed forward equalizer equalizes the second filtered signal; at least one converter for creating a data signal according to at least the first equalized signal and the second equalized signal; and at least one soft decision circuit for creating a soft decision signal according to said data signal, wherein said soft decision circuit cancels at least a portion of one or both of said first equalized signal and said second equalized signal. - View Dependent Claims (80, 81, 82, 83, 84, 85, 86, 87, 88, 89)
