摘要
A point-to-multipoint communication system based on cognitive radio TDMA is disclosed. The present invention is configured to support one-hop range communication by configuring a point-to-multipoint topology around a cognitive radio network base station, and further to support horizontal and vertical terminal communication by operating a sounding channel. It is possible to reduce the hassle of passing through the base station for communication between terminals and greatly increase the network transmission rate and transmission efficiency. In addition, by supporting 2-hop relay between the terminals, an output between the base station and the terminal is limited in order to minimize frequency interference to a major user. Thus, a reduced transmission distance can be expanded while minimizing a transmission output. The point-to-multipoint communication system includes a first terminal and a base station.
