Methods and apparatus for compensating for polarization loss in communications systems that use orthogonally spaced polarization. In one example, a signal processing method uses a statistical decorrelation process to separate out two orthogonally polarized desired signals from noisy received signals that ...
The only limitations are the gradual loss of polarization by the 1H spin reservoir, and the decay of the 1H magnetization during spin locking. The latter process proceeds on a time-scale (‘spin–lattice relaxation in the rotating frame’) which is much shorter than the 13C spin–lattice ...
The 2/spl times/2 polarization matrix was investigated in terms of path loss, cross-polarization and fading statistics. The results show a higher depolarization of the vertical polarized signals at higher frequency. No significant power correlation coefficients were measured for tramsmitter-receiver ...

An approximate formula is derived for the on-axis cross-polarization discrimination (XPD) of a symmetrical reflector antenna with random surface errors. This XPD depends on only two parameters, namely, the normalized r.m.s. surface error (/) and the polarization-loss efficiency (n)....

Within this wind speed regime, cross-polarized data showed no distinguishable loss of sensitivity and as such, cross-polarized data can be considered a good candidate for the retrieval of strong-to-severe wind speeds from satellite instruments. The upper limit of 45 m s???1 is defined by ...
(OCV) of the DMFC is usually below 0.8V, which depends on the operating conditions such as temperature andmethanol concentration. The voltage loss caused by methanol crossover is also illustrated inFigure 3. It can be observed that the polarization is reduced with an increase in the current ...
