An Inequality on the Capacity Region of Multiaccess Multipath Channels

The effects of multiaccess sources and time varying multipath are considered in analyzing a system in which multiple sources communicate with a fixed base station. We discuss detection and the use of stripping in a multiaccess multipath environment. We finally derive a capacity for these systems. It turns out that CDMA type systems are inherently capable (theoretically) of higher rates than systems such as slow frequency hopping that maintain orthogonality between users.
