| Abstract: | The method of PN code blind estimation for direct sequence spread spectrum(DS-SS)signal were analyzed.Three kinds of PN code blind estimation method for DS-SS signal were introduced,including the method based on eigen analysis of signal,the method based on characteristic polynomials of PN code and the method based on correlation operation.Based on the brief introduction of each algorithm's source,theoretical foundation and development process,the advantages and disadvantages of these algorithms are compared,and the development direction of PN code blind estimation research for DS-SS signal is also forecast. |
