Abstract
A method for filtering a signal having a series of symbols to be transmitted using the default coefficients, detecting occurrence of a series of consecutive common symbols followed by a different symbol in the series of symbols and based on detecting the occurrence, changing from the default coefficients to a second set of coefficients.
Claims21
A method, comprising:
- applying default coefficients to a transmit filter;
- filtering a signal to be transmitted using the default coefficients, said signal comprising a series of symbols;
- detecting occurrence of a series of consecutive common symbols followed by a different symbol;
- and
- based on detecting said occurrence, changing from the default coefficients to a second set of coefficients.
2 more elements
A transmitter, comprising:
- a dynamic equalizer;
- and
- a digital-to-analog converter coupled to said dynamic equalizer;
- wherein said dynamic equalizer is configured to implement a set of default coefficients and then change to a second set of coefficients upon detection of a series of consecutive common symbols followed by a different symbol.
1 more element
A serializer/deserializer, comprising:
- a parallel-to-serial converter;
- and
- a transmitter coupled to the parallel-to-serial converter, said transmitter configured to implement a set of default filter coefficients and then change to a second set of filter coefficients upon detection of a series of consecutive common symbols followed by a different symbol.
