Channel Capacity Analysis of Non-Orthogonal Multiple Access With OAM-MIMO System

IEEE Wireless Communications Letters, 2020
In this letter, an orbital angular momentum-based multiple-input multiple-output (OAM-MIMO) multiplexing system is integrated with non-orthogonal multiple access (NOMA) to enhance the user and sum channel capacities of the downlink NOMA for multiple ...

Quantum Multiple Access Channel

Chinese Physics Letters, 2001
We consider the transmission of classical information over a quantum channel by many senders, which is a generalization of the two-sender case. The channel capacity region is shown to be a convex hull bound by the von Neumann entropy and the conditional von Neumann entropies.

Channel-hopping multiple access

2000 IEEE International Conference on Communications. ICC 2000. Global Convergence Through Communications. Conference Record, 2002
The medium-access control (MAC) protocols for wireless networks proposed or implemented to date based on collision-avoidance handshakes between the sender and receiver either require carrier sensing or the assignment of unique codes to nodes to ensure that intended receivers hear data packets without interference from hidden sources.

Rate-Diverse Multiple Access Over Gaussian Channels

IEEE Transactions on Wireless Communications, 2023
In this work, we develop a pair of rate-diverse encoder and decoder for a two-user Gaussian multiple access channel (GMAC). The proposed scheme enables the users to transmit with the same codeword length but different coding rates under diverse user ...
