基于两分量变换的MIMO系统通信性能优化研究
Research on Communication Performance Optimization of MIMO Systems Based on Two-component Transformation
摘要
Abstract
A communication system based on two-component transformation is introduced and its application in improving anti-fading capability and reducing bit error rate is discussed.In traditional signal transmission methods,symbol modulation is closely related to physical resources and is easily affected by channel fading.Two-component transformation can effectively average signal distortion and reduce bit error rate by modulating different parts of the signal on independent physical resources.The mathematical model of two-component transformation is analyzed in detail and applied to Multiple Input Multiple Output(MIMO)systems,and a method to optimize the parameters of two-component transformation is proposed.Simulation results show that under reasonable transformation parameters,the proposed method can significantly improve the communication performance of the system.关键词
