Optical Space-Time Division Multiple Access

Journal of Lightwave Technology, 2012
This work presents an approach to multiple access for free-space laser communication (lasercom) called space-time division multiple access, which aggregates traffic from multiple users at the network edge. The objective is to share resources to lower the cost, size, weight, and power consumption per user, thereby making lasercom feasible for users that

Scale-time-code-division multiple access (STCDMA)

Proceedings of the 1996 Tactical Communications Conference. Ensuring Joint Force Superiority in the Information Age, 2002
In this work, a wavelet-based multiple access system, STCDMA (scale-time-code-division multiple access), which is based on the scale, time, and code orthogonality has been described and its performance has been analyzed for synchronous transmission in an AWGN channel.

Time division multiple access based on CAN

Proceedings of the 4th World Congress on Intelligent Control and Automation (Cat. No.02EX527), 2003
Real-time property is becoming an enabling technology for many important distributed applications. In this paper, related topic towards the design of distributed real-time control systems based on CAN have been presented. Through a simple systematic model, TDMA based on CAN has been realized to meet the demands of system real-time property.

A Satellite Time-Division Multiple-Access Experiment

IEEE Transactions on Communications, 1968
An important inherent advantage of communications via satellite is that large numbers of earth stations, separated by long distances, can communicate with each other simultaneously. Thus a satellite provides a multiple-access capability by nature of its physical location.

Multiple access and time division: a new look

International Symposium onInformation Theory, 2004. ISIT 2004. Proceedings., 2004
We rediscover the value of scheduled access through a detailed foray into the questions of throughput and energy consumption for MAC protocols in ad hoc wireless networks, where the optimal channel access scheduling is NP-complete. We propose a two-layered time-division heuristic of receiver activation and Group TDMA as polynomial-time solutions to ...

Space-Division Multiple Access Based on Time-Modulated Array

IEEE Antennas and Wireless Propagation Letters, 2015
A novel space-division multiple-access (SDMA) method is proposed by the multibeam characteristic of the time-modulated array (TMA). The TMA generates the fundamental and harmonic components pointing to different directions. For the uplink, the users in different directions transmit the signals with the same carrier frequency to the base station with ...
