| Abstract: | The paper proposes to estimate the spread spectrum sequence of the direct sequence spread spectral(DSSS) signals by chip-delay-multiply and correlation matrix Analysis.Theory analysis and computer simulations show that it can not only achieve the estimation of the spread spectral sequence,but also can give the synchronization information.The proposed method can fit in with the need of the low signal to noise ratio in the detection of the direct sequence spread spectral signals. |
