We drive a new frequency-domain adaptive algorithm by using a frequency-domain recursive least squares criterion, minimizing an error signal in the frequency-domain.
The frequency-domain DPSK (differential-phase-shift-keying) method for ultrafast laser pulses has been demonstrated by using an AOM-based pulse shaping technique for modulation and the spectral int
In exploring the possibility of providing digital mobile communications service to a large number of users, we have investigated a spreadspectrum modulation technique using frequency-hopped frequen
Mobile radio telephone systems are required to operate in a hostile environment compared to radio systems using terrestrial and satellite links.
Near future on-board telemetry, tracking and command (TT&C) equipment for secure communications will likely adopt frequency hopping (FH) instead of direct sequence (DS) spread spectrum (SS) tec
T w o major impairments of mobile radio communication systems are interference from other users and multipath fading.
The frequency of an InGaAsP DFB laser has been locked to the 2p sub (10) - 3d sub 5 transition of Argon atoms at 1.2960microns using the optogalvanic signal obtained from a commercial miniature gl
The frequency of an InGaAsP DFB laser has been locked to the 2 sub p10 - 3d sub s transition of Krypton atoms at 1.5339 microns using the optogalvanic effect.
A description of a crystal controlled, reactor-valve modulated f.m. transmitter of conventional design. The unit can provide r.f. output powers of 1, 3, 10, 20 or 50 kW in the range 88-108 Mc/s.
