Using techniques such as spatial division multiplexing (SDM), transmit beamforming, and space-time block coding (STBC), MIMO systems like IEEE 802.11n are conceived to increase dramatically throughput or to improve the reception range. Nevertheless, MIMO equipment in an indoor environment shows that the power level received in non-noisy conditions is not sufficient to explain the throughput variations...
This paper presents the realization of a wireless Gigabit Ethernet communication system operating in the 60 GHz band. The system architecture uses a single carrier modulation. A differential encoded binary phase shift keying modulation and a differential demodulation scheme are adopted for the intermediate frequency blocks. The baseband blocks use Reed-Solomon RS (255, 239) coding and decoding for...
This paper presents the design and the realization of a 60 GHz wireless Gigabit Ethernet communication system. A differential encoded binary phase shift keying modulation (DBPSK) and differential demodulation schemes are adopted for the IF blocks. The Gigabit Ethernet interface allows a high speed transfer of multimedia files via a 60 GHz wireless link. First measurement results are shown for 875...
This paper presents the realization of the digital block of a hardware simulator of MIMO propagation channels for UMTS and WLAN applications. The hardware simulator must reproduce the behavior of the radio propagation channel, thus making it possible to test "on table" the mobile radio equipments. The advantages are: low cost, short test duration, possibility to ensure the same test conditions...
