Method, device and system for processing multiple paths of single-carrier signals

Abstract

The invention relates to technologies in the field of communication, in particular to a method, a device and a system for processing multiple paths of single-carrier signals. The method comprises the following steps of: acquiring a plurality of training sequences which are in accordance with a sequence standard, wherein the sequence standard is that: self-correlation values of the training sequences are 0 in windows which are symmetric about zero time delay, and mutual correlation values of any two training sequences are 0 in the windows which are symmetric about the zero time delay; repeatedly arranging each training sequence which is in accordance with the sequence standard so as to form a path of training frame; and modulating each path of training frame into a single-carrier signal to form multiple paths of single-carrier signals. By the method, the device and the system for processing multiple paths of single-carrier signals, the training frames are formed by the plurality of training sequences acquired and in accordance with the sequence standard and are modulated into the single-carrier signals, so that the multiple paths of single-carrier signals are formed.

Description

technical field [0001] The present invention relates to the technology in the communication field, in particular to a method, device and system for processing multiple single-carrier signals. Background technique [0002] At present, in wireless communication systems and wired communication systems, the single-carrier signal linear modulation transmission system occupies an important share of the communication system market due to its maturity, simplicity, and high-speed characteristics in some channels, and is adopted by different communication standards. adopted by the agreement. This single-carrier symbol linear modulation transmission system is also used in many continuous or packet data services, such as terrestrial cable digital TV, satellite digital TV, microwave relay links, and satellite ground TDMA (Time Division Multiple Access, Time Division Multiple Access) ) group communication, etc. [0003] On the one hand, in a wireless communication system and a wired com...

Problems solved by technology

[0006] To sum up, the training frame should be suitable for applications such as synchronization, single-channel equalization, and multi-channel transmission equalization, which requires the training frame to have the characteristics of simultaneously meeting the requirements of synchronization, single-channel equalization, and multi-channel equalization. However, the current Synchronous training frames in existing technologies are only applicable to some of the above-mentioned application aspects
