Complexity Analysis of a Heuristic Method for Fixed-Frequency Assignment Including Adjacent Channel Interference

Autor: E. Gigi, V. Lyandres, R. Chavez-Santiago

Publikováno v: IEEE Transactions on Electromagnetic Compatibility. 50:203-208

In this paper, we extend an existing heuristic algorithm for fixed-frequency assignment in cellular communication networks in order to account for the effects of adjacent channel interference (ACI). Our algorithm utilizes estimations of carrier-to-in

Autor: E. Gigi, V. Lyandres, R. Chavez-Santiago

Publikováno v: 2005 IEEE International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications.

In this paper, the analysis of the time complexity that including adjacent channel interference in the computation of the channel-to-interference ratio for fixed frequency assignment in mobile communication systems is presented. A sequential algorith

The fixed channel assignment problem in GSM networks has been commonly modelled as a constraint satisfaction problem with binary channel separation constraints (graph-colouring model). However, it has been observed that heuristics using direct estima

Development of a new method for computing interference between low Earth orbit satellite networks and terrestrial radiocommunication systems

Autor: M. Lara-Barron, Valeri Kontorovich, R. Chavez-Santiago

Publikováno v: IEEE VTS 53rd Vehicular Technology Conference, Spring 2001. Proceedings (Cat. No.01CH37202).

The co-existence of the new low Earth orbit (LEO) satellite networks and other radiocommunication systems must be assured when designing and implementing them. However, to compute interference applying the classical link budget equations it is necess

Channel assignment for cellular mobile networks with nonuniform cells – an improved heuristic algorithm

Autor: E. Gigi, R. Chavez-Santiago, V. Lyandres

Publikováno v: IEE Proceedings - Communications. 153:61

A heuristic sequential algorithm for fixed channel assignment in cellular mobile networks with nonuniform cells, i.e., cells of different sizes and shapes, is presented. The channel assignment is treated as a nonbinary constraints satisfaction proble
