For the photodiodes PD0 and PD1, the photocurrents [I.
Therefore, the proposed system forces the photocurrents of the photodiodes PD0 and PD1 to be proportional to the cross-correlations and uses the cross-correlations to produce a modified photocurrent.
The output photocurrent of photodiode PD0 is proportional to [C.
The optical signal is measured from the photocurrent produced by the photodiodes.
Therefore, the proposed system uses the modified cross-correlation to produce a modified photocurrent, removing the MUI.
The noise variances in the modified photocurrent have various effects on system performance.
where bit = x is from the "0" or "1", PIIN, shot noise, and thermal noise are considered in the photocurrent analysis, the effect of the dark current is neglected, [I.
The photocurrent noise variances are based on statistically independent noise characteristics, because the PIIN, shot noise, and thermal noise are independent noises.
The photocurrent PIIN variance is shown in (13) and is defined as follows:
1](f), the photocurrent PIIN variance of the ONU can be written as
where q is the amount of charge created by the photocathode per detected gamma-ray, I is the average photocurrent per detector and [f.
R] is the photocurrent produced by light of pure wavelength [lambda] reflected from the mirror, and [I.
