Patent ID: 7489741

Claim:
A method to perform direct current (DC) compensation on an RF burst, wherein the RF burst is transmitted between a servicing base station and a wireless terminal, the method comprising: using an enCOder/DECoder (CODEC) processing module for: receiving the RF burst, wherein the RF burst is modulated according to either a first modulation format or a second modulation format; producing a plurality of samples from the RF burst; averaging at least some of the plurality of samples to produce a DC offset estimate; subtracting the DC offset estimate from each of the plurality of samples to produce a plurality of DC offset estimate subtracted samples; identifying the modulation format of the RF burst from the plurality of DC offset estimate subtracted samples; when the first modulation format is identified, demodulating the plurality of DC offset estimate subtracted samples; when the second modulation format is identified: adding the DC offset estimate to each of the plurality of DC offset estimate subtracted samples to produce a plurality of adjusted samples; and demodulating the plurality of adjusted samples.
