COMMUNICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/208147
Kind Code:
A1
Abstract:
Provided in the present application are a communication method and apparatus, which can be applied to a communication system of a UWB or 802.15 protocol. The method comprises: determining a first bit sequence, and outputting the first bit sequence, wherein the first bit sequence comprises a second bit sequence and N preset elements, the second bit sequence is determined according to a first key and an initial value, N is an integer greater than 0, and the values of the N preset elements are preset values. In the embodiments of the present application, preset values (i.e. said N preset elements) are inserted into a random sequence (i.e. said second bit sequence), such that the ratio of the amplitude of a main lobe of an autocorrelation function of the random sequence to the amplitude of the maximum side lobe thereof can be increased, the impact of noise, multi-path transmission, etc., on signal estimation can thus be reduced, and the problem of the accuracy for estimating the time of arrival of a signal being relatively low can then be solved.
