From the results in Table 3, we observe that the spectral combining leads to a significant improvement of the output SNR compared to the coherence based noise reduction.
Further evaluation of the reactor under single electricity-generating or hydrogen-producing mode indicated that further improvement of voltage output and reduction of electron losses were essential for efficient hydrogen generation.
The improvement of optical output power for LEDs with Au-coated SACNT thin film was due to the sheet resistance competition with the p-GaP, although there existed about 20% optical transmittance loss.
Passing soft information between different components in the receiver through both forward and feedback paths has shown a prominent improvement of the output over the iterations leading to error-rate performance close to theoretical limits.
Comparing with conventional quarter-wave plates designed by periodic multilayer structures, aperiodic quarter-wave plates show obvious improvement of transmissive output efficiency under the same parameters such as incident angle and photon energy.
Significant improvement of power output was obtained for the proposed new PEM fuel cells compared to the conventional ones under the same conditions except for the different gas distributors.
The quality improvement of the output is slight in the case of added noise with (just 0.05 PSNR dB), but it grows with the additional noise (the gain achieves the 0.52 dB of PSNR in the case of added noise with ).
