摘要： A radio communication system includes a plurality of radio devices and a plurality of terminal devices. The plurality of radio devices forms a mesh-type radio network. A plurality of terminal devices belong to a radio device and another plurality of terminal devices belong to another radio device. The plurality of radio devices each have global terminal connection information representing the connection between the terminal devices and the radio devices in the entire radio communication system. A radio device and another radio device relay radio communication between a terminal device and another terminal device using the global terminal connection information. When any of its subordinate terminal devices changes, each of the plurality of radio devices floods only the change information in the radio communication system.

摘要： The objective of the present invention is to improve transmission characteristics by transmitting data through multiple paths in a multihop radio network including multiple paths.In a source node 210 of (a), an encoder 212 performs communication path encoding, and a modulator 216 modulates. Unlike the prior art, however, a packetizing unit 214 designates relay paths and packetizes outputs from the encoder 212 for the respective paths, whereby signals are transmitted to multiple paths (in this case, two paths). A receiver (See (c)) of a destination node 260 demodulates the signals from the multiple paths using a demodulator 262. Thereafter, it depacketizes the packet of binary data hard-decided by a depacketizing/buffering unit 263 and then temporarily stores the depacketized pieces of data for respective paths in a buffer. A reliability data calculator 265 then diversity-combines, taking reliability data into account. A combiner/decoder 267 performs an error correction based on that combined data.
