Design of Antenna with Low Intensity RFID Wireless Network Signal

‏‎design of an analog ram (aram)chip with 10-bit resolution and low-power for signal processing in 0/5m cmos process‎‏

برای پردازش سیگنال آنالوگ در شبکه های عصبی ، معمولا نیاز به یک واحد حافظه آنالوگ احساس میشود که بدون احتیاج به ‏‎a/d‎‏ و‏‎d/a‎‏ بتواند بطور قابل انعطاف و مطمئن اطلاعات آنالوگ را در خود ذخیره کند. این واحد حافظه باید دارای دقت کافی ، سرعت بالا ، توان تلفاتی کم و سایز کوچک باشد و همچنین اطلاعات را برای زمان کافی در خود نگهدارد. برای پیاده سازی سیستمی که همه این قابلیتها را در خود داشته باشد، کوشش...

Low Frequency Reader and Antenna Design Using RFID

In the present era the technology is growing rapidly therefore it is necessary to adopt those methods in designing a system that are simpler and effective. The main concern is to design RFID system to secure entry points in an office environment. In this paper the work mainly specifies the design of RFID reader and antenna. The noncontact device of RFID system is more convenient approach instea...

Wireless sensor network design through genetic algorithm

In this paper, we study WSN design, as a multi-objective optimization problem using GA technique. We study the effects of GA parameters including population size, selection and crossover method and mutation probability on the design. Choosing suitable parameters is a trade-off between different network criteria and characteristics. Type of deployment, effect of network size, radio communication...

Full-duplex (Two-way) Wireless: Antenna Design and Signal Processing

Current wireless systems are one-way (similar to walkie-talkies), meaning that disjoint time or frequency segments are used to transmit and to receive. Realization of two-way wireless has challenged the research community for many years. This article establishes the theory and presents practical realization of two-way (true full-duplex) wireless. In contrast to the widely accepted beliefs, it i...
