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, 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.
