Design, analysis and applications of PAM-PN code and PPM-PN code

In the paper, PAM-PN code and PPM-PN code are designed and their autocorrelation function and power spectrum are deduced. And then, their features are compared and summarized, which shows that compared with single PN code, they have not only better characteristics of ranging and velocity measurement, but also better characteristics of ECCM. Furthermore, they are also easy to realize because of their periodicity. At last, as an application example of PPM-PN code, a PN code phase modulation and pseudorandom PPM combined fuse is introduced.
