Sum rate analysis of multiple-access neuro-spike communication channel with dynamic spiking threshold

On the Maximum Sum-rate Capacity of Cognitive Multiple Access Channel

We consider the communication scenario where multiple cognitive users wish to communicate to the same receiver, in the presence of primary transmission. The cognitive transmitters are assumed to have the side information about the primary transmission. The capacity region of cognitive users is formulated under the constraint that the capacity of primary transmission is not changed as if no cogn...

Dynamic Sharing of a Multiple Access Channel

In this paper we consider the mutual exclusion problem on a multiple access channel. Mutual exclusion is one of the fundamental problems in distributed computing. In the classic version of this problem, n processes perform a concurrent program which occasionally triggers some of them to use shared resources, such as memory, communication channel, device, etc. The goal is to design a distributed...

DF-based sum-rate optimization for multicarrier multiple access relay channel

We consider a system that consists of two sources, a half-duplex relay, and a destination. The sources want to transmit their messages reliably to the destination with the help of the relay. We study and analyze the performance of two transmission schemes in which the relay implements decode-andforward strategy. In the first scheme, we incorporate Orthogonal Frequency Division Multiple Access (...

Space-Time Multiple Access: Linear Growth in the Sum Rate

It is known that some of the spectacular capacity gains of using multiple antennas on a point-to-point rich scattering channel, namely linear growth with the number of antennas, can also be obtained in a multi-user environment. We give the constant of proportionality of linear growth in the sum-capacity when the number of users and antennas grow simultaneously, but with fewer users than antenna...
