Multiuser detection in multipath environments for variable spreading-factor CDMA systems.

Multiuser detection in multipath environments for variable spreading-factor CDMA systems.

A way to allow variable data rates in CDMA is by varying the spreading factor in accordance with the data rate requested by the user. A detection scheme suitable for multirate transmission is required in addition to one that combats multiple access interference of other users and intersymbol interfe...
