Nonlinear Signal Processing and its Applications to Telecommunications

This dissertation is primarily concerned with the estimation of nonlinear communication systems that are modeled by Volterra series. The major methods used for estimating the unknown channel parameters can be classified into two main categories: training-based and blind. First, orthobasis representation and training-based identification through the respective Fourier series are investigated for...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Optical Signal Processing and Telecommunication Applications

Optical packet switching has received considerable attention over the last few years. In this paper we discus how optical signal processing can play a role in photonic packet routing. Two examples are given. Firstly we discuss ultrafast wavelength switching at 160 Gbit/s in a single semiconductor optical amplifier. Secondly, an integrated photonic flip-flop is discussed. Finally a discussion is...

Optical Network Reconfiguration for Signal Processing Applications

This paper considers a class of embedded signal processing applications. To achieve realtime performance these applications must be executed on a parallel processor. The paper focuses on the multiring optical interconnection network used in the system and specifically on the performance gains associated with utilizing the bandwidth reconfiguration capabilities associated with the network. The n...
