ABSTRACT:
With the assumption of the bit number of one frame of a synchronous transport module to be S and the bit number of one radio frame in radio communication to be M, the bit number M of the radio frame is set to satisfy a relation S=K.M (K is a natural number other than 0). Hereby, the circuit construction of a SDH radio communiaction transmitter/receiver equipment is simplified and power consumption is reduced. In the case where a radio intermediate switching station is installed, the circuit construction of the intermediate station is simplified and power consumptuion is reduced.
