Patent ID: 7394881

Claim:
A radio receiver comprising: a low noise amplifier operably coupled to amplify inbound radio frequency (RF) signals to produce amplified inbound RF signals; down conversion module operably coupled to convert the amplified inbound RF signals into low intermediate frequency (IF) signals; analog to digital converter operably coupled to convert the low IF signals into digital low IF signals; and a digital demodulator operably coupled to convert the digital low IF signals into inbound digital symbols, wherein the digital demodulator includes: baseband conversion module operably coupled to convert the digital low IF signals into digital baseband signals; filtering module operably coupled to filter the digital baseband signals to produce filtered digital baseband signals; programmable equalizer operably coupled to equalize frequency response of the filtered digital baseband signals such that in-band frequency response of the radio receiver approximates frequency response of a square root raised cosine filter to produce adjusted digital baseband signals; COordinate Rotation DIgital Computer (CORDIC) module operably coupled to produce phase and magnitude information from the adjusted digital baseband signals; and demodulation module operably coupled to produce the inbound digital symbols from the phase and magnitude informnation.
