| Abstract: | Proposed in this paper is a multiple access technology based on bivariate Chirp modulation,which makes use of both the Chirp rate and the initial Chirp phase to furtherest suppress the multiple access interference with small system gain.When the Chirp rate differences are small,this method can ensure the orthogonality of multiple access signals by distinguishing different initial phases.Moreover,the effect of the mutual correlation of multiple access users' Chirp signals on the bit error rate(BER) is discus... |
