基于Kronecker积的无线通信系统参量分离方法
A Kronecker Product Based Parameter Separation Method for Wireless Communication Systems
摘要
Abstract
For the problem of transmitter nonlinearity and wireless multi-path fading channel in wireless communication systems,a combined estimation of the nonlinearity of power amplifier ( PA) and impulse re-sponse of wireless channel with the received signal is proposed. Firstly,a convolution matrix is constructed based on the training symbols and model structure of the nonlinearity,then once least squares ( LS) is used to estimate the coefficients of the model of the PA and actual transmitted symbols through the PA. Second-ly,the estimation of the impulse response of the wireless channel is obtained with another LS. And the inte-gration of the two estimations can be iterative or with direct summation and mean. Theoretical derivation and experimental results demonstrate that the method can be used in single-carrier or multi-carrier com-munication with oversampling technology,and can separate the nonlinearity of PA and impulse response of wireless channel effectively. The novel method can be used for the physical-layer radio frequency( RF) fingerprint authentication and reliable signal transmission.关键词
