This paper is the study of the QPSK (Quadrature Phase Shift keying) modulation technique using AWGN (Additive White Gaussian Noise) and Multipath Rayleigh fading channel. In QPSK scheme the authors ...
Optical vector analysis has emerged as a critical tool for characterising optical devices, enabling simultaneous measurement of amplitude and phase responses over wide bandwidths. This technique is ...
DENVER — A small startup claiming breakthroughs in phase-coherent filter modulation will be demonstrating its signal-processing techniques in analog pager bands later this year, as a prelude to ...
Permutation codes are mathematical constructs that utilise the properties of permutations to encode and protect information, with applications spanning powerline communications, flash memory storage ...
Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...
The Internet explosion caused a surge in demand for new telecommunication services. The next wave of demand will come from new applications like third-generation (3G) high-speed personal ...
