基于幅度谱编码的基函数生成算法性能分析
Performance Analysis of Amplitude Spectrum Coding Based Basis Function Generation Algorithm
摘要
Abstract
The fundamental and basis function generation algorithm of transform domain communication sys-tem ( TDCS) are analyzed firstly. On the basis of one-ary PN sequence phase randomization, the basis function generation algorithm based on amplitude spectrum coding is studied by using another one-ary PN sequence multiplied by the amplitude spectrum of basis function. The randomicity of this method is N( N is the length of basis function) times by that of traditional method,which will increase the ability of anti-in-tercepting and capacity of multiple access. The simulation results show that performance on multiple access communication BER( Bit Error Ratio) is better.关键词
