An Inequality on the Capacity Region of Multiaccess Multipath Channels
نویسنده
چکیده
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. Dedication This paper is dedicated to James L. Massey on the occasion of his 60th birthday. His works on coding, on multiaccess, and on information theory have all had an important impact on the ideas here.' May his 60's be as much fun and as much an inspirtation to all of us as his earlier decades.

Gaussian multiaccess channels with ISI: Capacity region and multiuser water-filling
The capacity region of a two-user Gaussian multiaccess channel with intersymbol interference (ISI), where the inputs pass through respective linear systems and are then superimposed before being corrupted by an additive Gaussian noise process, is found. A novel geometrical method is given to obtain the optimal input power spectral densities and the capacity region. This method can be viewed as ...

In multiaccess wireless systems, dynamic allocation of resources such as transmit power, bandwidths, and rates is an important means to deal with the time-varying nature of the environment. In this two-part paper, we consider the problem of optimal resource allocation from an information-theoretic point of view. We focus on the multiaccess fading channel with Gaussian noise, and define two noti...

In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...

متن کاملTotal Capacity of Multiaccess Vector Channels
The well known waterrlling power allocation policy maximizes the sum capacity of parallel Gaussian channels. We consider multiaccess vector channels with additive colored Gaussian noise and asymmetric user power constraints and completely characterize the sum capacity of this channel. We show that the sum capacity of the multiaccess vector channel is upper bounded by that of corresponding paral...
