Improvement of Direct Spreading Spectrum by Multi-Spreading Spectrum
In the direct spreading spectrum(DSS) the number of length of spreading is less, and the several errors will lead to sharp decrease of peak-to-sidelobe ratio and the errors sometimes cannot be corrected. To solve this problem, a new method of Multi-Spreading Spectrum (I.e. MSS) with error-correcting ability is proposed. The new method is combining several correlation receptions and majority algorithm and its performance on error-correcting is much more batter than the DSS, and the new MSS method also give more number of spreading length. MSS not only performs better than Direct Spreading Spectrum (DSS) in the similar condition, but also is easier to be realized.
