On the Bit Error Rate of Lightwave Systems
نویسندگان
چکیده
We revisit the problem of evaluating the performances of communication systems with optical ampliiers and a wideband optical lter. We compute the exact probability of error and the optimal threshold and compare them with those predicted by Gaussian approximations for ASK, FSK or DPSK modulations, both for ideal photodetectors and for the case where shot noise is signiicant.

Bit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)
In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...
متن کاملOn the Bit Error Rate of Lightwave Systems with Optical Amplifiers
We revisit the problem of evaluating the performances of communication systems with optical amplifiers and a wideband optical filter. We compute the exact probability of error and the optimal threshold and compare them with those predicted by Gaussian approximations for ASK, FSK or DPSK modulations, both for ideal photodetectors and for the case where shot noise is significant.
متن کاملA Product-Coded WDM Coding System - Communications, IEEE Transactions on
Forward error correction is a feasible approach to decline the bit error floor of lightwave systems, arising from the fact that a simple single-error-correcting code can reduce the error floor from O(P,) to O(P'). Here we propose a novel wavelength demultiplexer (WDM) coding system using product code to improve performances of WDM systems with an error floor caused by fiber dispersion or system...
متن کاملAn Estimation of Required Rotational Torque to Operate Horizontal Directional Drilling Using Rock Engineering Systems
Horizontal directional drilling (HDD) is widely used in soil and rock engineering. In a variety of conditions, it is necessary to estimate the torque required for performing the reaming operation. Nevertheless, there is not presently a convenient method to accomplish this task. In this paper, to overcome this difficulty based on the basic concepts of rock engineering systems (RES), a model for ...
متن کاملEffects of Four Wave Mixing on an Optical WDM System by using Dispersion Shifted Fibre
The trend toward higher bit rates in lightwave communication has interest in dispersion-shifted fibre to minimize dispersion penalties. At the same time optical amplifiers have increased interest in wavelength multiplexing. These two methods of increasing system capacity if used together can result in severe degradation due to fibre nonlinearity. So the effect of dispersion, input power, fibre ...
