Abstract
A receiver circuit of a cordless communication system has an analog signal processing section with a channel selection filter and a digital signal processing section which is connected downstream of the latter and has a group delay equalizer. The group delay equalizer is used to equalize the digital distortion caused by the channel selection filter.
Claims9
A receiver circuit for a cordless communication system, the receiver circuit comprising:
- an analog signal processing section having a channel selection filter;
- a digital signal processing section connected downstream of said analog signal process section, said digital signal processing section having a group delay equalizer for equalizing at least signal distortion caused by said channel selection filter;
- a limiter connected to said analog processing section;
- and
- a sampling stage operating in an oversampling mode and generating a digital output signal with a word length 1, said sampling stage connected between said limiter and said digital signal processing section.
2 more elements
A method for processing a received signal in a cordless communication system, which comprises the steps of:
- carrying out a channel selection using an analog channel selection filter;
- digitizing a received signal by signal limitation and oversampling of a limited signal, an output signal with a word length 1 being generated during the oversampling;
- and
- using a digital group delay equalizer for equalizing signal distortion caused by the analog channel selection filter.
