Abstract

The invention discloses a linearization analysis method of a nonlinear system, comprising: using the Bussgang theory to obtain the transfer characteristic function h(y) corresponding to the source signal x from the transmitting node to the first relay node sr ); Utilize the linear amplification theory to describe the transfer characteristic function h(y sr ) is linearly amplified to obtain the first relay processing function f r (y sr '); According to the first relay processing function, the first received signal y corresponding to the source signal is obtained from the first relay node to the receiving node rd . It can be seen that, in the above process, the power attenuation factor and the noise factor can be combined, so that the first received signal more truly reflects the nature of the source signal. In addition, the invention also discloses a linearized analysis system of a nonlinear system, and the effect is as above.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a linearization analysis method and system for a nonlinear system. Background technique

[0002] In the past few decades, wireless communication technology has developed rapidly, and has also made great progress in practical applications. In every technological revolution, communication technology will develop rapidly, and the size, cost and transmission reliability of communication equipment have been greatly improved.

[0003] The systems we are currently studying are all analyzed according to linear systems, because our general research mainly considers idealized linear amplifiers, but the actual systems are all nonlinear systems, and there are not only noises but also noises during signal transmission. There are factors such as power attenuation. In the prior art, the power attenuation factor and the noise factor are not combined, so that the analysis result cannot re...
