The paper proposes an effective algorithm to estimate the spread spectrum sequence of Direct Spread Spectrum Sequence (DSSS) signal, which is suitable for non-cooperative communication systems. Two measurement functions are suggested. One is used for sequence synchronization; the other is used for sequence estimation chip by chip. Only simple complex addition and multiplication are required in this algorithm. Both theoretic analysis and computer simulations show the effectiveness of this algorithm.
