Method and apparatus for frequency offset correction |
摘要 |
Coherent detection of high-speed digital wireless communications becomes more difficult when the frequencies of the transmitter and receiver oscillators do not coincide. A frequency-locked loop may be used to characterize this frequency offset by processing the samples received on a pilot channel. Rather than using the offset information thus derived to correct the frequency of the received signal, the invention realizes a considerable computational savings by applying a frequency correction to the despread pilot samples instead.
