Parallel interference cancellation in multiuser detection
Matti Latva‐aho, Jorma Lilleberg · 2002
The parallel interference cancellation (PIC) principle is a conceptually simple and yet effective method of parameter estimation and data detection in the presence of multiple-access and multipath interference. It unifies some of the known methods of data detection, complex channel coefficient estimation, as well as delay tracking in DS-CDMA receivers. The PIC method will be derived and some numerical results for data detection, channel coefficient estimation and delay tracking will be presented.
