A radio receiver includes a low noise amplifier, a down conversion module,
an analog to digital converter, and a digital demodulator. The digital
demodulator is operably coupled to convert the digital low IF signals
into inbound digital symbols and includes a baseband conversion module, a
filtering module, a programmable equalizer, a CORDIC module, and a
demodulation module. The programmable equalizer is operably coupled to
equalize phase and frequency response of filtered digital baseband
signals from the filtering module such that the phase and frequency
response of the filtered digital baseband signals approximates phase and
frequency response of a square root raised cosine filter to produce
adjusted digital baseband signals. The CORDIC module is operably coupled
to produce phase and magnitude information from the adjusted digital
baseband signals. The demodulation module is operably coupled to produce
the inbound digital symbols from the phase and magnitude information.
