    • 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.
    • 用于发送和接收全数字接收机的符号的同步方法和装置。 该方法包括以下步骤:在接收由基带处理芯片发送的采样信号之后,其由第二时钟源提供的时钟信号,数字信号处理器(DSP),其时钟信号由第一 时钟源,测量局部采样符号和空中接口符号之间的相移,并获取相移量; 根据相移量,调整数字模拟/模数转换器采样的采样机会; 并且当调整用于采样数字模拟/模数转换器的采样机会时,调整用于数据发送和接收DSP的接口时钟,以使DSP的数据发送和接收能够与 抽样。
