Title
(EN) THREE-CELL WIRELESS COMMUNICATION SYSTEM
(FR) SYSTEME DE TRANSMISSION SANS FIL A TROIS CELLULES
Abstract
(EN) A wireless communication system including a repeated pattern of cells (203) in which base station transmitters (204) and user station transmitters (202) for each cell may be assigned a spread-spectrum code for modulating radio signal communication in that cell. Radio signals used in that cell are spread across a bandwidth sufficiently wide that both base station receivers and user station receivers in an adjacent cell may distinguish communication which originates in one cell from another. Adjacent cells may use distinguishable frequencies and distinguishable codes, but it is sufficient if adjacent cells use distinguishable frequencies and identical codes. A repeated pattern of cells allows the codes each to be reused in a plurality of cells.
(FR) Système de transmission sans fil comprenant un modèle récurrent de cellules (203) dans lequel on peut attribuer aux émetteurs des stations de base (204) et aux émetteurs des stations d'utilisateur (202) pour chaque cellule un code d'étalement du spectre afin de moduler une transmission de signaux radio dans ladite cellule. Les signaux radio utilisés dans la cellule en question sont étalés sur une largeur de bande suffisamment vaste pour que les récepteurs des stations de base aussi bien que les récepteurs des stations d'utilisateur dans une cellule adjacente puissent distinguer une transmission émanant d'une cellule d'une transmission émanant d'une autre cellule. Les cellules adjacentes peuvent utiliser des fréquences distinguables et des codes distinguables, mais il suffit que des cellules adjacentes utilisent des fréquences distinguables et des codes identiques. Un modèle récurrent de cellules permet de réutiliser chaque code dans plusieurs cellules.
