Antiing multipath multiaddress interference technology in spread spectrum communications

Abstract

There are two kinds of interference in a communication system: multipath and multiaddress interference. Using A RAKE receiver in a direct sequence spread spectrum system is an efficient method of anti-multipath interference, and multistage interference cancellation technology we can be used for anti-multiaddress interference. Combining a RAKE receiver with multistage interference cancellation, multipath and multiaddress interference can be removed at the same time.
