PURPOSE:To include lots of information into a transmission signal by providing a synchronizing signal generating means generating a synchronizing signal and a transmission signal generating means generating a transmission signal to the transmission side and a matching filter for the synchronizing signal and a matching filter to the transmission signal to the reception side. CONSTITUTION:When a spread spectrum communication signal of a period series Ai is received and it is processed by a matching filter 1 of period series Ai, a signal represented by an autocorrelation function of the period series Ai is obtained as the output. The information signal subject to spread spectrum communication is reproduced from the signal represented by the autocorrelation function. On the other hand, the spread spectrum communication signal of the period series Ai is detoured to the spread spectrum communication system of the period series Aj and inputted to a matching filter 2 of the period series Aj, then a signal represented by the cross correlation function between the period series Ai and Aj is outputted as the output. The signal represented by the cross correlation function acts like an interference disturbing signal to the information signal reproduced by the autocorrelation function signal of the period series Aj in the matching filter 2. |
