Noise Reduction of OCDM Signals by Electrical Time Gating
Noise Reduction OCDM Signals Electrical Time Gating
2015/6/9
To reduce the MAI noises from the received OCDM signals, a new electrical time gating method has been designed and evaluated. The results show a bit-error rate improvement of up to over 10 8 .
Noise reduction for digital holograms in a discrete cosine transform (DCT) domain
digital hologram noise reduction discrete cosine transform holographic reconstruction
2011/5/9
This paper presents a method for reducing noise in a digital hologram, which occurs during
acquisition. The algorithm proposed initially transforms a digital hologram into frequency-domain
data thro...
