In this paper we evaluate the real-time performance of a MIMO-enhanced 802.11a transceiver based on analog combining techniques. The aim of this transceiver design is to achieve higher performance than conventional 802.11a systems while keeping costs and power consumption similar. Also, the demonstrator used to carry out this evaluation is presented, as well as its implementation over a dual band...
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...
This paper has reported on the design and development of an FPGA based 2times2 MIMO testbed employing commercially available MAX289 RF transceiver chips and in-house developed antennas. Details of the operation of various parts of this system have been described. A particular attention has been paid to symbol synchronization which is crucial to achieving the data demodulation, channel estimation,...
