摘　　要：一种崭新的信道编码技术ＴｕｒｂｏＣｏｄｅｓ（ＴＣ）以其优越的纠错性能很快在通信领域得到实际应用。本文讨论了这一技术在ＣＤＭＡ系统中的应用。由于采用了这种前向差错控制（ＦＥＣ）信道编码技术，使得ＣＤＭＡ系统具有了较好的抗远近效应性能。A new channel coding technology--Turbo Codes (TC), has been applied practically soon in the fields of communications with respect to its outstanding error-correcting performance. This paper discusses the application of this technology in CDMA system. The CDMA system attains the better performance of resisting near-far effective because of employing this forward error control (FEC) channel coding technology.
