The group delay dispersion (GDD) of a single AOD at 800nm wavelength is about 9300fs2. Based on the principle of angular dispersion of AOD and the prism,an approach that uses single prism pre-compensating an AOD for the temporal dispersion was designed and demonstrated by experiments.
3. Based on the rudimentary analysis about light in PCs, we do some research about the superprism effects in regular 1D periodic structures and the similar group-velocity effects in 1D nonperiodic structures, discuss the relation between spatial dispersion and temporal dispersion and analyze the conducting of light in some typical 1D nonperiodic structures.
The BER performance of rate 2/3 trellis coded 8DPSK OFDM over time dispersive channels is simulated. The design of trellis codes at different carriers numbers of OFDM is discussed.
We analyse and simulate the BER performance of rate 2/3 trellis coded 8DPSKOFDM over time dispersive channels. Design of trellis codes at different carriers numbers of OFDM is discussed.
The paper presents a trelliscoded orthogonal frequency division multiplex (TCOFDM) system,which combines OFDM with trelliscoded modulation for combating the effects of frequency selective and multipath fading of time dispersive channels.
A trellis coded orthogonal frequency division multiplex (TC OFDM) system, which combines OFDM with trellis coded modulation for combating the effects of frequency selective and multipath fading of time dispersive channels is presented.
The self-focusing of an axisymmetric beam propagating in a cubically nonlinear medium has been studied by computer simulation with allowance for the temporal dispersion of the nonlinear response, which is manifested for femtosecond laser pulses.
jejuni (n = 8), GM1 (n = 4), or GD1b (n = 4) showed electrophysiological features suggestive of demyelination with prolonged distal motor latencies and temporal dispersion/conduction block similar to GBS patients without these specific antibodies.
In the quasi-optical aberration-free approximation, a parabolic equation for the envelope of an electromagnetic wave packet propagating along a geometric optical ray in a smoothly inhomogeneous isotropic medium with time dispersion is obtained.
It is found that polarized states can be preserved for a long time, but the polarization dynamics in 10-40-nm-thick LB films is characterized by a considerable switching-time dispersion.
The spectrum of the backward reflected radiation is investigated as a function of the peak intensity of the pulse and the characteristics of the time dispersion of the medium.
We develop a mathematically consistent framework allowing (i) to constructively determine if a given time dispersive system can be extended to a conservative one; (ii) to construct that very conservative system-which we show is essentially unique.
We develop a Hamiltonian theory of a time dispersive and dissipative inhomogeneous medium, as described by a linear response equation respecting causality and power dissipation.
This paper analysis the dispersion features of various gratings and presents the concept of the RGTD(reflective grating time dispersion). On this basis, the first order diffraction formula of the optical pulse is demonstrated.
Intersymbol interference(ISI),caused by the multipath fading of HF channel,isthe main obsatcle in HF high speed data transmission.A single tone serial transmittingmethod is proposed as the countermeasure of ISI.A lot of research results on the algorithmsof HF MODEM are summarized. The digital implementation of the HF MODEM using theTMS320C30 high speed digital signal processor is reported also.
This paper supposes the concept of grating tencporal dispersion, and gives a sunoke abd bivel mefhod that is used to analyse the quadratic phase correction of the double gratings compressor,and discusses the compressing characters of the double gratings compressor for the linear frequency chirped optical pulses.
