Abstract
A radio communications transmission system in which the communication information is digitalized and impressed on a radio frequency carrier by means of frequency modulation and/or phase modulation and wherein at the receiving station the interference is recognized as amplitude modulation occurring at the output of the intermediate frequency stage and wherein when such interference occurrence is recognized the received data is identified as being faulty and is replaced by redundantly transmitted data which is received and stored at the receiving side so as to provide accurate transmission of data.
