Information transfer speed carried on spread spectrum measuring MSK-signal of perspective radio navigation system increase

Keywords:

E.V. Kuzmin


Spread spectrum signals with minimum shift keying (MSK) are find application in perspective radio navigation systems. Requirements of digital information transfer carried on spread spectrum measuring MSK-signal is important feature of perspective radio navigating system. In article deals with mathematical description of spread spectrum MSK-signals in case of additional digital modulation. Shannon’s limit of navigational-communication channel capacity for the describing task is estimated. Requirements of reference signal coherence are defined. The way of information transfer speed carried on spread spectrum measuring MSK-signal of perspective radio navigating system increasing is suggested. The noise-immunity analysis of suggested way is carried out.
