Abstract

The invention belongs to the technical field of communication, and in particular relates to a multi-carrier spread spectrum technology based on multi-carrier direct sequence spread spectrum code division multiple access (MC-DS-CDMA) and FFH-OFDM. A multi-carrier spread spectrum method based on fast frequency hopping, which takes into account the common characteristics of MC-DS-CDMA and FFH-OFDM, avoids the weakness of traditional MC-DS-CDMA without frequency diversity gain, and is effective in anti-fading, It has certain advantages in anti-interference, code division multiple access, and communication confidentiality.

Description

technical field

[0001] The invention belongs to the technical field of communication, in particular to a multi-carrier spread spectrum technology based on multi-carrier direct sequence spread spectrum code division multiple access (MC-DS-CDMA) and FFH-OFDM. Background technique

[0002] With the development of OFDM and spread spectrum communication, a new communication technology - multi-carrier spread spectrum technology has emerged. This technology combines OFDM technology and spread spectrum technology, and takes into account the advantages of the two technologies in anti-multipath, anti-interference, code division multiple access, and confidentiality, and has become a hot spot in current communication technology research. According to its structure and the different forms of spread spectrum, it can be roughly divided into four types: MC-CDMA, MC-DS-CDMA, MT-CDMA, and two-dimensional spread spectrum technology. Among them, MC-DS-CDMA is a time-domain spread spectrum tech...
