PURPOSE:To remove multipath interference in a system where digital information are transmitted in parallel through the use of a spectrum direct diffusion code division multiplex (DSSS-CDM) system. CONSTITUTION:A pseudo multipath signal (the output of pseudo multipath generator 9) is generated by using a signal (the output of a remodulator 6) obtained by divisionally multiplexing again a spectrum direction diffusion code through the use of a signal which is once decoded on a reception-side and by using the amplitude of the multipath and delay information (the output of a correlator 8). Thus, the influence of interference by the multipath is reduced by extracting the pseudo multipath signal from reception input (the output of a delay unit 10). |
