Method and system for radio transmission of digital signals

摘要

In a radio system which operates using code division multiplex (CDMA) the interference in the training sequences, for example interblock sequences, of all the K subscribers in the received signal is overcome before data detection at the receiving end. The interference in the training sequences of all K subscribers is modeled using the estimated channel pulse responses and, finally, is subtracted from the received signal. The method and apparatus can be used in CDMA mobile radio systems, in particular with joint detection.
