This paper presents a new test platform that aims to test new generations of Near Field Communication (NFC) products implementing Very High Bit Rate (VHBR), up to 6.78Mb/s. New generations of NFC products, and especially electronic passports, will implement new data rates above 848kb/s in order to facilitate data exchange and increase security. This increase in data rates up to 6.78Mb/sby modulating...
A radio telescope analyzes the radio frequency (RF) received from celestial objects. It consists of an antenna, a receiver, and a spectrometer. The spectrometer converts the time domain into the frequency domain with an FFT operation. A solar radio burst observation requires a high-speed FFT. This paper proposes a P parallel N point FFT for fixed point data based on a six-step algorithm. We analyze...
In this paper, a low-cost hardware implementation of a Look-up-Table(LUT) based digital predistorter (DPD) using Field Programmable Gate Array(FPGA) for power amplifier linearization is proposed. The LUT predistoter is implemented in Altera Stratix II DSP Development Board to simulate the inverse model for memoryless wide-band RF power amplifiers. The parameters of the LUT predistoter are identified...
