Abstract
A signal acquisition method and device. Positioning signals as received are divided into at least two groups and frequency compensation is performed on each group of positioning signals. Each frequency compensated group of positioning signals is divided into at least two signal blocks, and an averaging operation is performed on the signal blocks in each group of signals, so as to obtain block-averaged groups of positioning signals. An acquisition result is determined based on the block-averaged groups of positioning signals. Noise power of each block-averaged group of signals is reduced. Therefore, noise power of received positioning signals can be reduced. This may improve signal-to-noise ratio of received signals and acquisition sensitivity of a receiver. Therefore, acquisition success rate of weak signals is increased.
