Signal processing method and device

The invention discloses a signal processing method and a signal processing device, which are used for realizing signal compensation based on relative group delay, improving the accuracy of TOA (Time of Arrival) estimation and finally improving the UE (User Equipment) positioning accuracy. The signal processing method provided by the invention comprises the following steps: performing channel estimation processing based on a received positioning reference signal PRS to obtain a frequency domain channel response; based on the frequency domain channel response, determining a differential value of relative group delay of a sub-band; compensating a locally received PRS signal or a frequency domain channel response based on the differential value of the sub-band relative group delay; or reporting the difference value of the sub-band relative to the group delay to the sending end, and compensating the sending signal by the sending end. 本申请公开了信号处理方法及装置，用以实现基于相对群时延进行信号补偿，提高TOA估计的精确度，从而最终提高UE定位精度。本申请提供的信号处理方法包括：基于接收到的定
