Our network is a chain of encoder-decoder networks. Figures 15 and 16 explain the details of the two encoderdecoders used in the bootstrap and iterative net part. Fig. 17 gives implementation details for the refinement net. The encoder-decoders for the bootstrap and iterative net use additional inputs which come from previous predictions. Some of these inputs, like warped images or depth from o...

This paper presents the comparative performance of different detection and coding schemes for spectral-amplitude-coded optical code division multiple access (SACOCDMA) system. SAC-OCDMA systems are receiving more attention because of their ability to completely eliminate multiple access interference (MAI). Fiber Bragg grating (FBGs) are used as encoder/decoder. Experimental simulation was carri...

This article puts forward parallel forward error correction(FEC) codec for 10 Gb/s Ethernet passive optical network (10G-EPON) , which adopts 8-parallel algorithm based on improved state space transformation (SST) method for Reed-Solomon (RS) encoder and 9-parallel algorithm based on enhanced degree computationless modified Euclid’s (EDCME) algorithm to solve the key equation for RS decoder.

We report on the design, fabrication and performance of a matching integrated optical CDMA encoder-decoder pair based on holographic Bragg reflector technology. Simultaneous encoding/decoding operation of two multiple wavelength-hopping time-spreading codes was successfully demonstrated and shown to support two error-free OCDMA links at OC-24. A double-pass scheme was employed in the devices to...

One fiber radio scheme using shifted prime codes for interference elimination is proposed for optical code-division multiple-access (OCDMA) network. By taking advantage of the cyclic property of the shifted prime codes in the same code groups, the proposed compact decoder is low cost and suitable to be used in the task manager node in the applications of wireless sensor networks. The performanc...

In this paper, we apply the perfect difference codes in wireless infrared systems considering the diffuse indoor optical wireless configuration. The bit error rate performance of the uplink wireless infrared system using Gaussian approximations is analyzed taking into account the effects of multiple-access interference, the ambient light noise, and the dark current. The proposed system also use...

I propose encoder and decoder architectures for entanglement-assisted (EA) quantum low-density parity-check (LDPC) codes suitable for all-optical implementation. I show that two basic gates needed for EA quantum error correction, namely, controlled-NOT (CNOT) and Hadamard gates can be implemented based on Mach-Zehnder interferometer. In addition, I show that EA quantum LDPC codes from balanced ...

Future lithography systems must produce chips with smaller feature sizes, while maintaining throughput comparable to today’s optical lithography systems. This places stringent data handling requirements on the design of any direct-write maskless system. To achieve the throughput of one wafer layer per minute with a direct-write maskless lithography system, using 22 nm pixels for 45 nm technolog...
