In order to expand the application domain of field programmable gate arrays (FPGA), a highly-integrated wireless configuration scheme is presented by transfering the configuration data with RF method. To fulfill the configuration system, three key hardware portions are necessary, including the configuration controller in FPGA, the RF data channel and the configuration host. In this paper, the central...
This paper presents a baseband and RF transceiver at 5.2-GHz band for wireless LAN systems. The baseband unit supports 2×2 MIMO-OFDM with an 80-MHz channel and provides the maximum data rate of 600 Mbps. The wider channel of 80 MHz is a candidate technology for the next WLAN standardization of IEEE802.11ac. OFDM tends to cause high peak PAPR for the wider channel and distort power amplifier performance...
In this paper the implementation of a configurable hardware for an UHF RF identification (RFID) tag emulator at 868 MHz is demonstrated. The tag emulator is used for reader performance verification under worst case conditions. The characteristics of a tag can precisely be emulated: reflection coefficient dependent on received signal strength, variation of the frequency, and timing jitter of the backscattered...
