In future high-speed self-routing photonic networks based on all-optical time division multiplexing (OTDM) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. In this paper we propose a self-routing OTDM node structure composed of an all-optical router and demultiplex...
in this paper the problem of minimizing the total transmitting power subject to a fixedtotal bit rate in ofdm systems is considered. upper bounds on transmitting power and bit rate ofeach subcarrier can also be taken into account. in practice, the number of bits of each subcarriershould be integer and nonnegative. in this paper an analytical optimal solution is derived for thecase of assuming t...
Application of quantum-dot is a promising technology for implementing digital systems at nano-scale. Quantum-dot Cellular Automata (QCA) is a system with low power consumption and a potentially high density and regularity. Also, QCA supports the new devices with nanotechnology architecture. This technique works </...
In network steganography methods based on packet length, the length of the packets is used as a carrier for exchanging secret messages. Existing methods in this area are vulnerable against detections due to abnormal network traffic behaviors. The main goal of this paper is to propose a method which has great resistance to network traffic detections. In the first proposed method, the sender embe...
In this paper, a Dual-Bit Parallel Adder (DBPA) based on minority function using Carbon-Nanotube Field-Effect Transistor (CNFET) is proposed. The possibility of having several threshold voltage (Vt) levels by CNFETs leading to wide use of them in designing of digital circuits. The main goal of designing proposed DBPA is to reduce critical path delay in adder circuits. The proposed design positi...
مبدل های آنالوگ به دیجیتال با سرعت بالا و دقت پایین (چهار بیت) در ارتباطات پهن باند ، لینک های سریال ، گیرنده مبتنی بر مدولاسیون ofdm و گیرنده چند باندی مبتنی بر مدولاسیون ofdm مورد استفاده قرار می گیرد. در این پایان نامه سعی شده است که یک مبدل آنالوگ به دیجیتال از نوع تقریب متوالی با دقت 4 بیت و سرعت 715 مگاهرتز طراحی و شبیه سازی شود. پیکربندی استفاده شده برای این مبدل از نوع 2-bit/step می باش...
