A method to perform DC compensation on a Radio Frequency (RF) burst
transmitted between a servicing base station and a wireless terminal in a
cellular wireless communication system that first receives the RF burst
modulated according to either a first or second modulation format.
Samples from the RF burst, or taken from the training sequence, are
produced and averaged to produce a DC offset estimate. The DC offset
estimate is then subtracted from each of the samples. The modulation
format of RF burst may then be identified from the samples. Depending on
the identified modulation format, the DC offset estimate may be re-added
to the samples when a particular modulation format is identified as the
modulation format of the RF burst. This decision is made based on how
well various components within the wireless terminal perform DC offset
compensation.
