Title:
RADIO LINE ALLOCATION METHOD AND RADIO LINE ALLOCATION DEVICE
Document Type and Number:
Japanese Patent JP2017038310
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To select a communication mode and a polarization mode so that radio resources (bandwidth, electric power and polarization) which can be utilized on the whole system are simultaneously utilized at a maximum.SOLUTION: A radio line allocation method of a radio communication system consisting of a plurality of terminal stations utilizing one of main polarization, orthogonal polarization and both of the main polarization and orthogonal polarization in simultaneous use for a communication line, a node device relaying communications of the terminal stations, and a radio line allocation device allocating communication lines used for those communication comprises: a step of determining, for each of polarization modes of the main polarization, orthogonal polarization and both, a communication mode as a combination of a modulation/demodulation system and an error correction encoding system with a used band and used electric power balanced; a step of determining a polarization mode having the best balance between an inter-polarization used band and used electric power; and a step of allocating a communication line consisting of the determined polarization mode and the communication mode to a free band.SELECTED DRAWING: Figure 1
