Radio transmission system comprising a master station and slave stations, each comprising an error correcting section including error correcting methods

摘要

In a radio transmission system having a master station and plural slave stations connected to the master station via a radio transmission path, the master station has a master error correcting section including plural master error correcting methods and each of the slave stations has a slave error correcting section including plural slave error correcting methods identical with the master error correcting methods. A detection section detects an upward error rate for an upward transmission path to produce a detected error rate. A monitoring section compares the detected error rate with a predetermined reference value to produce degradation information when the detected error rate is larger than the predetermined reference value. Responsive to the degradation information, a master switching section supplies the master error correcting section with a switch control signal. A master radio section sends the switch control signal via a downward transmission path to the slave stations. In each of the slave stations, a slave radio section receives the switch control signal to produce a received switch control signal. A slave switching section supplies the slave error correcting section with the received switch control signal.
