Introduction. Numerous modern infocommunication systems are based on the spread spectrum technology, i. e., on the use of signals with a large bandwidth-duration product. Many such systems implement discrete signals, which are sequences of standard p

To effectively receive a useful broadband signal, it is necessary to compensate for distortions caused by the complex frequency-dependent coefficient of the receiving and transmitting antenna, multiplicative interference and noise from the heterogene

The pulse position detection of the pseudorandom time-hopping (TH) pseudolite is critical for the participative global navigation satellite system (GNSS) receivers. The conventional method to detect the pseudorandom TH pulse positions of the received

When the source code is copied and pasted or modified, there will be a lot of identical or similar code snippets in the software system, which are called code clones. Because code clones are believed to result in undesirable maintainability of softwa

A code recovery method of a global navigation satellite system (GNSS) authorized service (AS) signal component is described under the condition of a high signal-to-noise ratio. The correctness of the spreading code verification can be used to monitor

A class of fractional-order hyperchaotic system is introduced and its basic dynamical properties are investigated by means of theoretical analysis and numerical simulation. Systemic sensitivity to the orders of all involved derivatives is analyzed by

This paper concerns the folklore statement that ``entropy is a lower bound for compression''. More precisely we derive from the entropy theorem a simple proof of a pointwise inequality firstly stated by Ornstein and Shields and which is the almost-su
