METHOD, APPARATUS AND SYSTEM FOR SENDING AND RECEIVING PREAMBLE SEQUENCE

Document Type and Number:

WIPO Patent Application WO/2016/065554

Kind Code:

A1

Abstract:

Provided are a method, apparatus and system for sending and receiving a preamble sequence. The method for sending a preamble sequence includes: generating, by a sending end, a frequency offset estimation sequence, the frequency offset estimation sequence including N sub-sequences of which the length is M, N being a positive integer which is greater than or equal to 2, and M being a positive integer; generating, by the sending end, a prefix and a suffix based on the frequency offset estimation sequence; adding, by the sending end, the prefix and the suffix to a front part and a rear part of the frequency offset estimation sequence respectively to form a preamble sequence, the prefix and the suffix being used for resisting multipath interference; and adding, by the sending end, the preamble sequence into a data packet, and sending the data packet to a receiving end. According to the method, by adding the prefix and the suffix to the frequency offset estimation sequence at the sending end, a frequency offset estimation sequence which is higher in multipath interference resistance is provided.
