where Δø is the delay, Δn is the birefringence of the prism, and θ/2 is the divergence half angle of light transmitted through the prism. The two orthogonal states are separated by the prism and then focused by a separate lens into the tissue. This allows backscattering from both or...
A logarithmic scale has been used for the spectral density so that the shapes of the spectra can be discerned over a wide range of Hs. The model-free directional parameters defined in Section 8.03.4.1.2(ii)(c) are used to estimate the mean direction and spread directly from the measured...
Thus a specific set of pre-scalers is referred to here as a ‘pre-scaler profile’, with the mapping encoder enabling switching between different pre-scaler profiles in the following manner. Pre-scaler profiles may be added to the register space connected to the multiplexer and assigned to a...
(two dimensional) at least one additional dimension is provided by utilizing a co-set selection techniques in accordance with the various embodiments of the invention. For example, the use of a dimensional modulation space >>2 can be used to increase the possible number of subsets, increasing ...
Orthogonal Delay Scale Space Modulation: A New Technique for Wideband Time-Varying Channels Orthogonal Time Frequency Space (OTFS) modulation is a recently proposed scheme for time-varying narrowband channels in terrestrial radio-frequency communi...

Assuming that the input light is completely polarized on a time scale much shorter than the modulation period, we can represent a general input or output SOP by a normalized Jones vector of the form (9.21)J→=[aTMaTE]=[cosθexp(jϕ/2)sinθexp(−jϕ/2)], whose two components ...
However, confined by the characteristic of Alamouti space-time coding, it has to use clusters to expand scale while increasing the number of relay nodes, which adds the difficulty of coordination among relay nodes. Meanwhile, the orthogonal complex signals with both full diversity gain and full ...
The orthogonal frequency-division multiplexing (OFDM) mode with a linear frequency modulation (LFM) signal as the baseband waveform has been widely studied and applied in multiple-input multiple-output (MIMO) radar systems. However, its high sidelobe levels after pulse compression affect the target ...
Finally, index modulation (IM) is added to the idea of joint RIS and DF relaying. For indoor and outdoor environments and various frequency bands, the benefits of RIS deployment are examined in [15]. For both single- and multiple-RIS, the system is tested. It has been demonstrated that ...
