Intermodulation and Harmonic Distortion in Traveling-Wave Semiconductor Cascade Laser

Hasnul H. Hashim; Stavros Iezekiel IEEE Transactions on Microwave Theory and Techniques, 2010

Intermodulation distortion and harmonic distortion in a traveling-wave semiconductor cascade laser (TWSCL) is investigated. The TWSCL is an extension of the idea of a semiconductor cascade laser where transmission lines connect the laser diodes in a cascade followed by a terminating impedance. The nonlinear behavior of the TWSCL is analyzed using harmonic balance and determined to be comparable to a ...


An innovative method of Text Steganography

Shashank Gupta; Rachit Jain 2015 Third International Conference on Image Information Processing (ICIIP), 2015

Text Steganography is a field of hiding text messages into multimedia (e.g. image) documents. In this method we apply DWT on input image to divide it into four sub-band. We will work on low frequency band. After hiding the text information the picture has been compressed for reducing the memory. The method which is used for the compression is Discrete ...

Experimental observation of different types of vector solitons such as the bright-bright, dark-dark, and dark-bright vector soliton in single mode fiber lasers is reported. Experimental techniques for observing each of the vector solitons are explained. Special features of the vector solitons in fiber lasers are numerically simulated and compared with the experiments.


More accurate pinhole camera calibration with imperfect planar target

Klaus H. Strobl; Gerd Hirzinger 2011 IEEE International Conference on Computer Vision Workshops (ICCV Workshops), 2011

This paper presents a novel approach to camera calibration that improves final accuracy with respect to standard methods using precision planar targets, even if now inaccurate, unmeasured, roughly planar targets can be used. The work builds on a recent trend in camera calibration, namely concurrent optimization of scene structure together with the intrinsic camera parameters [4, 8, 1]. A novel ...


Performance of turbo equalizers for optical PMD channels

M. Jager; T. Rankl; J. Speidel; Henning Bulow; F. Buchali Journal of Lightwave Technology, 2006

This paper investigates the performance of iterative (turbo) equalization to mitigate the effects of a polarization-mode dispersion (PMD) in nonreturn-to- zero (NRZ) intensity-modulated optical-fiber transmission systems. A PMD can lead to severe distortions in the received electrical signal and is a key limiter for the development of high-bit-rate transmission over currently used fibers. In order to reduce the distortions due ...

  • Statistical Noise in Communications

    Optical Bit Error Rate: An Estimation Methodology provides an analytical methodology to the estimation of bit error rate of optical digital signals. This presents an extremely important subject in the design of optical communications systems and networks, yet previous to the publication of this book the topic had not been covered holistically. The text lays out an easy- to-understand analytical approach to a highly important and complex subject: bit error rate (BER) estimation of a transmitted signal with a focus on optical transmission. It includes coverage of such important topics as impairments on DWDM optical signals, causes of signal distortion, and identification and estimation of the signal quality by statistical estimation of the bit error rate. The book includes numerous illustrations and examples to make a difficult topic easy to understand. This edition includes a CD-ROM with run-time simulations from a vendor that provides commercial software for the industry.

    Chapter 6 provides detailed analysis of a fiber-wireless reverse link when more than one multiuser RF signals are transmitted over fiber. The concept of nonlinearity induced co-channel interference is explained in this chapter and detailed expressions for signal to distortion, noise and (multiuser) interference ratios are derived for both wireless systems considering optical link nonlinearity and wireless channel fading. Simulation results are also shown. Note that the reverse link is asynchronous compared forward link.

  • Multiuser CDMA Fi-Wi Systems

    A multiuser CDMA fiber-wireless system will experience all the following impairments: (1) nonlinear distortions in the optical channel; (2) multipath dispersion in the wireless channel; and (3) multiuser interference in the air interface. Optical and electrical noise will also be added in both channels. In addition, each user will experience individual multipath fading while the nonlinear distortion would be a function of total number of users in the system because nonlinear optical channel is shared among them. This chapter shows how all these impairments can be estimated and equalized using a very interesting iterative technique. This algorithm could add value for fourth generation (4G) wireless networks.

  • Joint Equalization for the Fi-Wi Channel

    When nonlinear distortion of the fiber channel and the multipath dispersion of the wireless channel are combined together, equalization is a very interesting challenge. These two distortions have to be dealt jointly when the baseband DSP approach is used. In this chapter a novel algorithm is developed to equalize the both the static nonlinearity of the optical channel and the dynamic multipath dispersion of the wireless channel. A patented equalizer structure is described that compensates for the linear and nonlinear portions separately.

  • Subcarrier-Multiplexed ROF Downlink

    Chapter 5 provides detailed analysis of a fiber-wireless forward link when more than one multiuser RF signals are transmitted over fiber. Wi-Fi and cellular radio signals are considered. The concept of nonlinearity induced co- channel interference is introduced in this chapter. Detailed mathematical expressions are derived for signal to distortion, noise and (multiuser) interference ratios for both wireless systems considering optical link nonlinearity and wireless channel fading. Simulation results are also shown.

  • Joint Estimation of the Fi-Wi Channel

    It is an interesting scenario when the nonlinear distortion of the fiber channel and the multipath dispersion of the wireless channel are combined together. These have to be dealt jointly when the baseband DSP approach is used due to the concatenated nature of the fiber-wireless channel. Note that there is no down conversion done at the radio access point therefore no baseband DSP is possible. In this chapter a novel algorithm is developed to estimate both the nonlinearity coefficients of optical channel as well as impulse response of the wireless channel by observing the input output digital signals.
