| 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 despreading.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. |
