| Abstract: | This paper proposes a problem that the error tolerance property of spread spectrum sequence influences the performance of spread spectrum system.Then the relation is analyzed between the error tolerance property and the correlation property of binary sequence when correlation detection is proceeded, and the theoretical limitation of error tolerance is given.Finally, we investigate the relationship between the determination of the output decision threshold of correlation,the probability of correlation peak detection and the error tolerance of the spread spectrum sequence. |
