摘要:

A new digital PN signal correlator, which is more suitable and easier to implement, using digital integrated circuits is proposed in this paper. This digital PN signal correlator consists of a bit matched filter, an exclusive OR operator, and a counter. The statistical properties and the error rate performance of the digital PN signal correlator are analyzed and discussed in detail. The results show that this digital PN signal correlator will suffer slight SNR degradation., (maximum degradation is about —2 dB) as compared with the conventional analog PN signal correlator for small values ofEb/N0(<0.75), but for highEb/N0,even a very significant SNR improvement can be achieved.
