Abstract
A method for canceling an interference signal by using a parallel multi-stage structure in a code division multiple access (CDMA) system, includes the steps of: a) delaying a receiving signal; b) receiving and predicting data and channel parameter from the individual user; c) regenerating the interference signal of the individual user by using the data and the channel parameter predicted by the multiple receiving and predicting; and d) canceling all the interference signals delayed and transferred through the delaying by the interference signal regenerated through the multiple interference regeneration.
