Efficient implementation of 90° phase shifter in FPGA
In this article, we present an efficient way of implementing 90° phase shifter using Hilbert transformer with canonic signed digit (CSD) coefficients in FPGA. It is implemented using 27-tap symmetric finite impulse response (FIR) filter. Representing the filter coefficients by CSD eliminates the need for multipliers and the filter is implemented using shifters and adders/subtractors. The simula...
متن کاملEfficient Reversible Multiplier Circuit Implementation in Fpga
Reversible logic gates are very much in demand for the future computing technologies as they are known to produce zero power dissipation under ideal conditions. The applications of reversible logic gates include ultralow power, nano computing, quantum computing, low power CMOS design, optical information processing, bioinformatics etc. This paper proposes an improved design of a multiplier usin...
متن کاملFPGA Based Efficient Implementation of Viterbi Decoder
It is well known that data transmissions over wireless channels are affected by attenuation, distortion, interference and noise, which affect the receiver’s ability to receive correct information. Convolutional encoding with Viterbi decoding is a powerful method for forward error detection and correction. It has been widely deployed in many wireless communication systems to improve the limited ...
متن کاملAn Efficient Fpga Implementation of Aes Algorithm
The Advanced Encryption Standard can be programmed in software or built with pure hardware. But Field Programmable Gate Arrays (FPGAS) offer a faster and more customizable solution, since the entire algorithm can be executed in a single tick of clock cycle. This research deals with the implementation of AES algorithm in FPGA using Verilog Language. Software is used for simulation and optimizati...
متن کاملEfficient FPGA Implementation of Block Cipher MISTY1
NESSIE is a 3-year research project (2000-2002). The goal of the project is to put forward some algorithms to obtain a set of the next generation of cryptographic primitives. In order to achieve this objective, the project needs to evaluate mathematical security levels and software/hardware implementations. This paper investigates the significance of an FPGA implementation of the block cipher M...
