PROBLEM TO BE SOLVED: To provide a communication system in which random access is possible and setting of a total communication time within a prescribed communication time limit is easily set. SOLUTION: A transmitter 1S being a slave set is provided with a pseudo noise generating section 4 generating a pseudo noise code, a timing decision section 5 to decide a transmission timing of transmission data synchronously with a pseudo noise code generated by the pseudo noise generating section 4 and a data transmission section 6 conducting data transmission for a prescribed number of times within a prescribed time based on the timing decided by the timing decision section 5. Furthermore, a receiver 1R acting like a master station is provided with a pseudo noise generating section 8 generating a pseudo noise code corresponding to a plurality of the transmitters 1S and a data reception section 9 receiving the transmission data synchronously with the pseudo noise ode code generated by the pseudo noise generating section 8. |
