The periodic chirp signal modulated by the pseudo-noise code (chirp-PC) is proposed as the ranging signal of LEO enhanced GNSS. The coupling characteristic of Doppler and delay in chirp-PC can make the search frequency grid less than the traditional BPSK signal with the same acquisition ...

Code Division Multiple Access (CDMA) is a suitable multi-access technology for UAV networking, but low spectrum utilization limits its application. In this study, we use a Pseudo-Noise (PN) code shifting modulation method to improve the spectrum utilization of CDMA signals, which makes it more ...
While the objective of military communication systems is to provide resistance against jamming, civilian systems use the codes to provide resistance against multipath propagation or to separate channels in a code division multiplexing system. One of the most common systems using direct sequence technology...
In order to reduce the time of acquisition pseudo noise code in GPS receiver, the conventional acquisition method slide correlation in the time domain was analyzed.为缩短GPS接收机捕获伪随机码的时间 ,分析了与时域滑动相关的常规捕获方法 ; With the wide application of Spread Spectrum Communication and...

1.An apparatus for pseudo noise (PN) code phase acquisition comprising:an oscillator;an analog to digital converter adapted to receive a baseband signal having a PN code phase, said analog to digital converter being adapted to sample said baseband signal at a rate controlled by said oscillator ...
Because the generalized modified prime sequence codes (GMPSC) is used as pseudo noise (PN) codes for CSK in the previous work, the code efficiency becomes low. Thus, It is difficult to improve the symbol error rate performance of CSK. In this paper, the use of the PN code with high ...
