Abstract

The invention relates to a receiver circuit and method capable of accurately estimating signal time bias. A method applied to a receiver circuit includes: performing a cross-correlation operation on at least one time domain signal on at least one receiving path of the receiver circuit according to a local sequence signal to estimate at least one signal time offset of the at least one time domain signal as at least one time offset compensation; and performing time offset compensation on the at least one time domain signal of the at least one receiving path according to the at least one time offset compensation amount.

Description

technical field [0001] The present invention relates to a time offset estimation mechanism, in particular to a time offset estimation method and device for a receiver circuit. Background technique [0002] Generally speaking, the crystal oscillation frequency of the traditional transmitting end circuit and the traditional receiving end circuit are not exactly the same, and this will cause frequency offset and time offset in the signal received by the traditional receiving end circuit. (time offset), if the clock signal of the carrier signal and the clock signal used for signal sampling are of the same source, the time offset can be compensated according to the result of the frequency offset. Conversely, if the two clock signals are If the sources are different, the time offset cannot be compensated according to the result of the frequency offset, and the time offset must be estimated separately. Therefore, for the situation where the clock signals are from the same source, ...
