Abstract

In this paper, DS / CDMA (code division DS) system with anti-interference and the role of data encryption, multi-rate signal transmission of several programs to Rayleigh fading channel transmission, for example, narrowband and wideband CDMA based channel Rayleigh number of different paths, indicating a multi-rate signal system, different programs have different results, by software simulation shows that, OVFS scheme in Rayleigh fading channels under its multi-channel processing gain and the number of fading paths on encryption performance of multi-rate systems have a major impact, broadband system encryption performance is better than narrowband systems. Multi-modulation is also a feasible option, but it handles the user´s high-speed data encryption performance is significantly worse than other programs.
