Abstract
A radio burst signal transmission system operates to switch between a first control process for optimizing the number of bits added per symbol depending on the probability of successful reception of a successful reception indication signal and a second control process for divisionally sending a burst signal, depending on the state of a propagation path between a base station and a terminal. A fragmentation control request determining circuit in each of the base station and the terminal determines an average value and a variance value of time-depending variations of an error of a propagation path function, and a burst signal length of a reception burst signal, from the reception burst signal that is received from the terminal and the base station, and determines a pointer for requesting switching from the first control process to the second control process. When the terminal and the base station receive the request from the base station and the terminal, respectively, a fragmentation control circuit switches from the first control process to the second control process and sends a transmission burst signal to the base station and the terminal if the burst signal length of the reception burst signal exceeds a predetermined value.
