Problems solved by technology

[0003] However, since UQPSK only has two independent channels, it limits the type of information data that can be carried simultaneously in asymmetric transmission and the configuration of bandwidth, which affects the design of the communication system and cannot satisfy the design of the communication system to the greatest extent.

Abstract

The invention discloses an asymmetric communication method and device. In the asymmetric communication sending method, the method includes: performing channel coding on multiple channels of information data; performing framing and spreading operations on the information data after multi-channel channel coding. In the asymmetric communication sending device, it includes: a channel coding module, which performs channel coding on multiple information data streams to be transmitted; a multiplexing module, which frames the multiple channel coded information data streams into one channel with a fixed frame length and format frame data streams, and send them after segmented spread spectrum and band-pass modulation. By adopting the invention, the asymmetric transmission of more than two channels of information data is realized, and the transmission requirements of communication symbols with higher safety requirements can be met.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to an asymmetric communication method and device, in particular to an asymmetric communication method and device for transmitting information with high security requirements. Background technique [0002] In asymmetric communication, UQPSK technology is usually used. Such as figure 1 As shown, UQPSK technology adopts PSK modulation, and the signal space of PSK modulation is a two-dimensional orthogonal space, which contains two mutually orthogonal components, where ψ 1 (t) = cosω 0 t, is the in-phase component, ψ 2 (t)=sinω 0 t, is the orthogonal component. Therefore, the current UQPSK technology can transmit two different channels of information at the same time. The data streams of the two channels of information can have different code rates, and are transmitted in two irrelevant independent information data streams, and the power ratio ρ of the data of the two channels...
