Abstract:

A read-only holographic memory for digital data storage is experimentally demonstrated. Techniques for coding and decoding of optical signals, and the interface techniques between the optical memory and a personal computer are described. The performance of the optical memory and the techniques for improving the bit error rate (BER) are presented.

Abstract:

Optical wireless communications (OWC) are among the best alternative techniques for transmitting information-laden optical radiation across a free-space channel from one place to another. DC-biased optical OFDM (DCO-OFDM) is a technique that sacrifices the power efficiency to transmit unipolar OFDM signals. The primary drawback with DCO-OFDM is its clipping noise, which causes distortion and lowers the bit error rate (BER). Thus, in this paper, we show the performance of DCO with different coded techniques to improve the BER in additive white Gaussian noise (AWGN) for IMDD systems. The experimental results show that the coded DCO-OFDM has the best performance. Furthermore, turbo coding has the best coding technique added to the DCO-OFDM system.

Abstract:

In this paper, we investigate the performance of Spectral Amplitude Coding Optical Code Division Multiple Access technique based on Free Space Optical channel. SAC OCDMA is one of the most popular multiplexing techniques since many years and FSO is gaining popularity and is very useful especially in point to point communication. The system presented in this paper utilizes Walsh Hadamard code as signature code. The coder and decoder structures are based on optical filters of fiber Bragg gratings (FBGs). This system focuses on the performance analysis of FSO based systems for subtropical regions. This paper demonstrates the error rate performance in the form of eye diagrams/BER under varying channel gain and link distances. Five cases have been taken which shows that SAC OCDMA FSO system is reliable even for distances sufficient to overcome the last mile problem.

Abstract:

Complex atmospheric environment seriously affect the quality of wireless of information transmission. In order to improve the wireless optical communication quality, and reduce the influence of attenuation, flicker, angle misalignment caused by atmospheric scattering, absorption, turbulence, beam expander, mismatch, atmospheric channel model is established while coding techniques for error control in wireless optical communication was researched into.The improvement result of error rate by error correction coding in different SNR situations was obtained. The results showed that the LDPC coding can significantly reduce the BER. For Gaussian channel, SNR can be reduced 8 dB when BER is 10-6; For wireless optical communication , LDPC codes can make the error rate reduced by 4-5 orders of magnitude.
