Patent ID: 7254198

Claim:
A receiver system comprising: an analog pre-filter comprising analog filtering circuitry that operates according to a transfer function (b 1 s+1)/(a 2 s 2 +a 1 s+1) for analog filtering a symbol-information-carrying input analog signal, or a first intermediate analog signal generated from the input analog signal, to produce a filtered analog signal with reduced intersymbol interference where a 1 , a 2 , and b 1 are non-zero filter parameters, and s is a frequency-transform variable; an analog-to-digital converter for converting the filtered analog signal, or a second intermediate analog signal generated from the filtered analog signal, into an initial digital signal; an equalizer for equalizing the initial digital signal, or an intermediate digital signal generated from the initial digital signal, to produce an equalized digital signal as a stream of equalized digital values; and a decoder for converting the equalized digital values, or intermediate digital values generated from the equalized digital values, into a stream of symbols.
