This paper presents a low TX noise transmitter with digital modulated power amplifier (DPA) for UHF RFID reader System-on-Chip. With I/Q digital signals directly modulated on DPA, the transmitter eliminates the pulse shaping filter, up-conversion mixer and power amplifier driver, which are dominant noise contributors in a conventional RFID transmitter. A switch-mode power amplifier cell is adopted...
Big data processing is receiving significant amount of interest as an important technology to reveal the information behind the data, such as trends, characteristics, etc. MapReduce is one of the most popular distributed parallel data processing framework. However, some high-end applications, especially some scientific analyses have both data-intensive and computation intensive features. Therefore,...
