A space-division time-division multiple access scheme for high throughput provisioning in WLANs
IEEE International Conference on Communications, 2005. ICC 2005. 2005, 2005Directional antennas may dramatically increase the capacity of a wireless LAN by allowing several stations to simultaneously communicate. Since deployment of directive/smart antennas on the customer's terminals is awkward (for technological, cost, robustness, and convenience reasons) it is of interest to deploy advanced antenna solutions only at the ...

Time Division Multiple Access Systems and Matrix Decomposition
1991We discuss the time slot assignment problem in satellite communication. First we derive an optimal solution of the corresponding mathematical problem which, however, will turn out to be impracticable. Then we consider a modified problem, but this is NP-hard. We describe some heuristics for this modified problem.

Spread Spectrum and Time Division Multiple Access Satellite Communications
IEEE Transactions on Communications, 1977Although time division multiple access (TDMA) satellite communication provides the highest traffic capacity per satellite and offers efficient transmission of a wide variety of services, it suffers from network timing and ranging requirements and message security.

STAP for space/code/time division multiple access systems
2004In this chapter, linear JD techniques were presented as an application of STAP in the field of mobile radio communications. STAP was performed on the UL of a cellular SD/TD/CDMA system by adaptively equalising the multiuser system channel matrix, which contains the spatio-temporal channel impulse responses between all transmitting MS and the receiving ...
