Abstract: | Using the eigenanalysis-based algorithm to blind estimate the spreading sequence of DSSS signal in multipath is studied in this paper.Firstly,a transmission model of DSSS signal in multipath is introduced.Then the eigenanalysis-based algorithm is used to estimate the spreading sequence.At last,simulations are presented to verify the effectiveness of the method in multipath. |
