Abstract
Methods and apparatus are described for interference cancellation of interference components of a time domain signal in the frequency domain. A time domain sequence is received, and a plurality of overlapping time domain segments is generated from the time domain sequence. Frequency offset compensation to compensate for frequency offset associated with a serving cell is performed in the time domain, and the overlapping time domain segments are then converted to the frequency domain. Additional frequency offset compensation may be performed to compensation for the frequency offset associated with interfering cells.
