Modern communications systems are heavily reliant on statistical techniques to recover
information in the presence of noise and interference. One of the mathematical structures …

Different pseudo-random or pseudo-noise (PN) as well as orthogonal sequences that can
be used as spreading codes for code division multiple access (CDMA) cellular networks or …

Recently, there has been a renewed interest in optical code-division multiple access
(OCDMA) due to its potential for offering increased levels of security at ultrahigh data rates …

We derive new bounds on the aperiodic total squared correlation (ATSC) of binary antipodal
signature sets for any number of signatures K and any signature length L. We then present …

We derive new bounds on the periodic (cyclic) total squared correlation (PTSC) of binary
antipodal signature sets for any number of signatures K and any signature length L. Optimal …

Pseudo-Random or pseudo-noise and Orthogonal Spreading sequences are widely used in
the Wideband Code Division Multiple Access (WCDMA) systems using Rake receiver. This …

Feature Issue on Optical Code Division Multiple Access The ability to access and modify
optical phase with high resolution is opening exciting new opportunities in the optical …

We analyze the effectivity of different pseudo noise (PN) and orthogonal sequences for
encrypting speech signals in terms of perceptual intelligence. Speech signal can be viewed …

The superframing option of the recent DVB-S2X standard specifies, for the so-called SF-Pilot
fields, the use of the orthogonal set of Walsh-Hadamard (WH) sequences. In order to exploit …

Time-Domain Reflectometry (TDR) RFID tags are passive, chipless tags that use
discontinuities along a transmission line to create reflections. The discontinuities may be …
