摘要
A method for tracking a residual frequency offset for a single carrier-frequency domain equalizer system includes: determining a pilot from the data and known pilot data, adding the determined pilot to the leading part of the data, copying a part of the frame of the data after a block and adding it before the block, and generating a preamble to construct one frame; eliminating a cyclic prefix, processing signals per an FFT block, extracting the preamble, and performing an initial channel estimation; updating a channel estimation, performing channel compensation, receiving a pilot, calculating an average phase of all the pilots in one FFT block, updating the channel estimation, performing an IFFT operation, extracting data, and recovering the original digital signal from the data.
