Abstract
A method and apparatus for adjusting symbol timing and/or symbol interval range of a receive burst of data within a radio receiver include processing that begins by receiving a radio frequency signal that includes bursts of data. The process then continues by determining a frequency offset for the burst of data based on a difference between the transmitter processing rate and a receiver processing rate. The processing then continues by determining a symbol timing offset and/or a symbol interval range offset based on the frequency offset. The process then proceeds by adjusting the initial symbol positioning and/or the symbol interval range offset of a burst of data based on the symbol timing offset.
