Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0042] Such as figure 1 As shown, this embodiment provides a communication method with information transmission weight, which specifically includes the following steps:

[0043] Step S1: The n groups of serial data streams S to be modulated and transmitted 1 (t),S 2 (t),...,S n (t), the modulation domain is assigned according to the weight coefficients corresponding to each group of serial data streams and used to measure the importance of data information; in this embodiment, the importance of information contained in each group of data streams is not equal, and the weight coefficient to measure the importance of information, and the jth group of data stream S j (t) has a weight coefficient denoted as A j ;

[0044] Step S2: performing numerical processing on the n groups of serial data streams according to the corresponding modulation fields to fo...

Abstract

The invention relates to a communication method with information transmission weight. The method comprises the following steps: distributing modulation domains to multiple groups of serial data code streams to be modulated and transmitted according to the weight coefficients; processing the serial data code streams according to the corresponding modulation domains to form a synthesized data stream; and then implementing modulated transmission on the synthesized data stream, and finally receiving and restoring a merged data code stream from a channel through two different methods. According to the communication method disclosed by the invention, the data code stream with higher information weight can occupy a wider modulation domain under limited channel resources, and thus more excellent signal-to-noise ratio can be achieved.

Description

technical field [0001] The invention relates to the communication field, in particular to a communication method with information transmission weight. Background technique [0002] In communication applications, various information has different importance, and conventional communication technology often does not distinguish the importance of information, but adopts equal transmission. In the case of noise interference in the channel, since all information is transmitted equally, the loss of important information will greatly reduce the communication quality. Contents of the invention [0003] In view of this, the object of the present invention is to propose a communication method with information transmission weight to overcome the defects in the prior art. [0004] The present invention adopts the following solutions to realize: a communication method with information transmission weight, comprising the following steps: [0005] Step S1: The n groups of serial data st...
