【摘要】 比较了传统扩频序列Ｇｏｌｄ码与混沌扩频序列的传输性能，并进行了计算机仿真。结果表明，混沌序列作为扩频序列不仅数目大，而且其误码率优于Ｇｏｌｄ码。讨论了两种混沌序列分别作为扩频序列时，表现出差异较大的传输特性，说明存在一个混沌系统和参数的选取问题。更多还原

【Abstract】 The selection of the spread spectrum code is one of the key problems in the directsequence spread spectrum communication system.The transmission character between the conventional spread spectrum sequence and the chaotic spread spectrum sequence is compared. It is shown from the computer simulations that, as for the spreading spectrum codes,the amount of the chaotic sequences is larger and the BER is much better than those of the conventional Gold sequences.And the performances of the two different types of chaotic sequences are also discussed in this paper.更多还原
