Optimization of Co-channel Interference Ratio (CCIR) for Omni-Directional Antenna in Mobile Computing
Due to the insufficiency of available bandwidth and the continuously growing demand for cellular communication services, there are many cells using same frequency band. All the cell using the same channel are physically located apart by at least reused distance, even though the power level is controlled carefully so that such “co-channels” do not create a problem for each other, there is still ...
متن کاملTerrestrial Television Broadcasting in Bands above 2 Ghz
Experimental amplitude-modulation terrestrial television broadcasting systems in Band 10 at 12 GHz have been set up in the Federal Republic of Germany [CCIR, 1974-78a], in the Netherlands [CCIR, 1974-78b], and in Switzerland [CCIR, 1974-78c] for system G, and in Japan for system M [CCIR, 1974-78d and e]. Further, an operational station for the same broadcasting system has been working in Japan ...
متن کاملCharacterization of the cciIR quorum-sensing system in Burkholderia cenocepacia.
Several transmissible Burkholderia cenocepacia strains that infect multiple cystic fibrosis patients contain a genomic island designated as the cenocepacia island (cci). The cci contains a predicted N-acylhomoserine lactone (AHL) synthase gene, cciI, and a predicted response regulator gene, cciR. AHL production profiles indicated that CciI catalyzes the synthesis of N-hexanoyl-l-homoserine lact...
متن کامل=yUg ⊗U ′ g ′;
1. Let G be a finite group. Let VecG be the category whose objects are C-vector bundles on G which are G-equivariant for the conjugation action of G on G. For U ∈ VecG let Ug denote the fibre of U at g ∈ G; the G-equivariant structure on U is given by isomorphisms ψ x : Uy −→ Uxyx−1 for any x, y ∈ G. For U,U ′ ∈ VecG we define U ∗U ′ ∈ VecG as follows: for y ∈ G, we have (U ∗U )y = ⊕(g,g′)∈G×G;...
متن کاملNoise Assessment and Mitigation for Loran for Aviation
The United States released the technical report on the ability of Loran to mitigate the effects of a GPS outage in December 2004. The report indicated that the current Loran system, with reasonable upgrades and modifications, could provide backup to GPS for aviation, maritime and timing users. The conclusion was based on the results of the analysis of many significant hazards to Loran usage. On...
