AI Technical Summary

Technical Problem

The high peak-to-average power ratio (PAPR) of signals generated by ZC sequences leads to high energy consumption or power limitation in the transmission of signals by terminal devices, which is difficult to effectively reduce with existing technologies.

Method used

Design a new sequence by generating a first sequence by summing the elements of the first and second values, such that the magnitude of the generated signal is constant while reducing PAPR.

Benefits of technology

This achieves a reduction in the peak-to-average power ratio (PAPR) of the signal while maintaining a constant modulus value, thereby reducing the energy consumption and power limitations of terminal devices.

Abstract

The application relates to the communication technical field, and discloses a communication method, device and system. The method comprises the following steps: a first communication device generates a first signal according to a first sequence, and transmits the first signal; wherein the nth element of the first sequence is obtained according to a first value and a second value, the first value is obtained according to the sum of at least one element in a first set, and the second value is obtained according to the sum of at least one element in a second set; n = 0, 1, 2,..., L-1, L = 2 l or L = 2 l -1, and l is an integer greater than or equal to 1. By using the above method, a new sequence (such as the first sequence) is designed, so that the signal generated according to the first sequence has a constant modulus value and a low PAPR.
