A synchronization method and device for transmit and receive symbols of an all-digital receiver. The method comprises the steps of: after receiving a sampling signal sent by a baseband processing chip, the clock signal of which is provided by a second clock source, a digital signal processor (DSP), the clock signal of which is provided by a first clock source, measuring a phase shift between a local sampling symbol and an air interface symbol, and acquiring the phase shift amount; according to the phase shift amount, adjusting a sampling opportunity for the sampling of a digital-analogue/analogue-digital converter; and when the sampling opportunity for the sampling of the digital-analogue/analogue-digital converter has been adjusted, adjusting an interface clock for data transmitting and receiving of the DSP so as to enable the data transmitting and receiving of the DSP to be synchronized with the sampling.
