摘要
Abstract
To improve the parallel despreading spectral efficiency and power efficiency, a parallel spread spectrum transmission scheme is proposed which is based on inner product operation and characterized by linear operator spreading,associative parallel spread spectrum transmission and the distributive parallel de-spreading. Compared with classical parallel spreading and relevant despreading scheme and classical parallel spreading matched filtering despreading scheme,the proposed scheme improves the spectral efficiency and power efficiency by 2 096 128 times and 1 048 576 times,respectively. In the condition of 8 × randn(1, length( b) ) interference and 64 bit parallel spread spectrum transmission,100 000 large sample test results show the statistical average error rate and the standard deviation are 0. 000 0 and 0. 000 7,respectively.关键词
