摘　　要：采用直序扩频的通信系统具有较高的抗干扰能力,但通信信息速率会大幅下降。因此,在通信速率和抗干扰之间找到一个平衡点,是扩频通信系统的一个重要技术问题。文中提出了一种CCSK编码解码技术,该技术可以有效地提高扩频通信系统的通信速率。Communication system using Direct Sequence Spread Spectrum processes stronger anti-interference ability, while the communication rate is decreased significantly. It is an important technical issue to balance the communication rate and the anti- interference ability. A coding and decoding technology of CCSK was proposed in the paper, which can improve effectively the communication rate of Spread Spectrum Communication system.
