Abstract :
A novel system for concurrently transmitting audio signals and digital codes from an AM radio station to each receiver is presented. Experiments for sending a still picture from the AM radio station to the receiver have been carried out to check whether the present system is satisfactory. Digital codecs were transmitted at a baud rate of 300 b/s with 2-φ to 4-φ phase-shift keying, and the bit and block error rates were on the order of a few percent
