OPTIMAL CARRIER SHARING IN WIRELESS TDMA

Journal of Interconnection Networks, 2001
To improve efficiency, we allow a carrier in a TDMA (Time Division Multiple Access) network to be shared by adjacent cells. This sharing of time slots is seriously hampered by the lack of synchronization in distinct cells. We study packing algorithms that overcome this obstacle by clustering calls.

CC-TDMA: Coloring- and Coding-Based Multi-Channel TDMA Scheduling for Wireless Ad Hoc Networks

2007 IEEE Wireless Communications and Networking Conference, 2007
This paper addresses the issue of transmission scheduling in multi-channel wireless ad hoc networks. The authors propose a multi-channel time division multiple access (TDMA) scheduling based on edge coloring and algebraic coding theory, called CC-TDMA.

High-speed TDMA techniques

Optical Fiber Communication Conference. Technical Digest Postconference Edition. Trends in Optics and Photonics Vol.37 (IEEE Cat. No. 00CH37079), 2002
High-speed time division multi-access (TDMA) optical communication systems will be necessary to meet the growing need for bandwidth-on-demand services in local and metropolitan area networks. Recently, many of the technological building blocks necessary to implement such a network have been demonstrated in research laboratories.

Design of a block time bounded TDMA (BTB-TDMA) MAC protocol for UANets

Ocean Engineering, 2011
Abstract In this paper, a Block Time Bounded Time Division Multiple Access (BTB-TDMA) medium access control (MAC) protocol is proposed for mobile underwater nodes (UNs) in underwater acoustic networks (UANets). The BTB-TDMA determines transmission schedule of UNs based on UNs' estimated propagation delays (EPDs), reflecting on UNs' mobility ...

CDMA & TDMA BASED NEURAL NETS

International Journal of Neural Systems, 2001
CDMA and TDMA telecommunication techniques were established long time ago, but they have acquired a renewed presence due to the rapidly increasing mobile phones demand. In this paper, we are going to see they are suitable for neural nets, if we leave the concept "connection" between processing units and we adopt the concept "messages" exchanged ...
