a new technique for calculation of the projected range distribution of implanted ions in solis state materials
روش جدید برای محاسبه ی تابع چگالی احتمال عمق نفوذ یون های پرتاب شده در نیمه هادی ها
کاشت یون نقش بسیار مهمی در ساخت انواع ادوات نیمه هادی و مدارات مجتمع ایفا می کند و شبیه سازی کاشت یون و محاسبه ی تابع چگالی احتمال عمق نفوذ یون ها یکی از مبنای اصلی در طراحی VLSI است در این نوشتار نیز یک مدل فیزیکی جدید ...
A Comprehensive Performance Analysis of Direct Detection Receivers in WDMA Systems
In this work the performance of a wavelength division multiple access (WDMA) system with direct detection receiver is investigated. For this purpose, the probability of error in a WDMA network with OOK modulation considering ...
Investigation of Coherent Multicarrier Code Division Multiple Access for Optical Access Networks
Orthogonal frequency division multiplexing (OFDM) has proved to be a promising technique to increase the reach and the bit rate both in long-haul communications and in passive optical networks. This paper, for the first time,
A Blind Hammerstein Diversity Combining Technique for Flat Fading Channels
Diversity combining techniques play an important role in combating the destructive effects of channel
fading in wireless communication systems. In this work we present a blind diversity combining technique
for ...
A Hammerstein Diversity Combining Technique
In wireless communication channels fading phenomenon imposes serious limitations upon the system
performance. Diversity combining is a well known fading compensation technique. In this paper we propose a
diversity ...
A Nonlinear Signal Processing Method for Diversity Combining Using Hammerstein Type Filter
Wireless communication systems suffer from the destructive
effects of channel fading. In this paper we propose a nonlinear
signal processing method for diversity combining based on a
Hammerstein type ...
A Nonlinear Equalization Technique for Frequency Selective Fading Channels
Abstract—We propose a new equalization technique based on nonlinear Hammerstein type filters to mitigate the intersymbol interference (ISI) effect. This technique is a nonlinear generalization of the linear equalizer. In ...
Performance Analysis of Optical CDMA Systems Utilizing Optical Encoding in Presence of Interference and Receiver Noises
Abstract. In this paper, performance of incoherent and
asynchronous optical CDMA (OCDMA) systems employing
“optical encoding” is investigated and the results are
compared with the results obtained when ...
جدا سازي كور مدولاسيونهاي مخابراتي با استفاده از بردارهاي ماشين تكيه گاه
جدا سازی کور مدولاسیونهای مخابراتی با استفاده از بردارهای ماشین تکیه گاه
در این مقاله سیستمی برای تشخیص نوع مدولاسیون پیشنهاد میشود که قادر است بدون شناخت اولیه از پارامترهای سیگنال ارسالی، 9 مدولاسیون از خانواده مدولاسیونهای فاز، دامنه و فاز-دامنه را شناسایی کند.
