SIGNAL PROCESSING METHOD AND APPARATUS

WIPO Patent Application WO/2024/051245

A1

Provided in the present application are a signal processing method and apparatus. The method comprises: a sending apparatus generating a first signal according to a first sequence and N data symbols, wherein the first sequence includes L elements, the maximum periodic auto-correlation sidelobe of the first sequence is less than or equal to a first threshold value, each data symbol among the N data symbols includes L chips arranged in sequence, the L chips arranged in sequence include chips bearing pulses, the chips bearing the pulses correspond, on a one-to-one basis, to elements, element values of which are specified values, in the first sequence, and N and L are both positive integers; the sending apparatus sending the first signal to a receiving apparatus; and the receiving apparatus parsing the first signal. By means of the method and apparatus provided in the present application, the situation where pulses borne by chips with opposite polarities among overlapping chips offset each other can be reduced, such that the packet error rate of a system can be reduced, and the anti-interference performance of the system is improved, thereby improving the communication quality of the system.
