M9. UWB and WiFi 802.11p channel measurements in frequency domain (April 2015).

M8. IR measurement in time domain (December 2014). The IR measurement performed in 2013 revealed some shortcomings of the IR measurement setup (e.g. limited modulation depth of the Mach-Zehnder modulator or large coupling loses between optical fibers and optical sets (lenses)) resulting in very small SNR. For the new measurements the coupling loses were reduced by the modification and improvement of the mechanical parts of the transmitting (TX) and receiving (RX) lenses leading to better focusation of the optical beams into the optical fibers.

M7. UWB measurement in both the time and frequency domain for comparison purpose (November 2014). Because the comparison of the frequency and time domain UWB channel analysis has been (according our best knowledge) published briefly only in one paper, we performed comparative measurements keeping the fixed antenna positions for the both domain. The channel transfer functions were measured using VNA E5071C ENA, while the CIR measurement was done using the high speed (12 Gbps) bit sequence generator built in BER tester MP1800A and Oscilloscope DPO 72004C. This approach brings some advantages compared to M2 (e.g. correlation gain, uniformly distributed power over the time) and will be used for future measurements.

M6. The same MMW measurement in frequency domain as in M5 but with the Quinstar low noise preamplifier QLW-50754530-I2 (purchased from grant funds) and with application of the extended calibration technique using MMW attenuator in order to get larger SNR (September and October 2014).

M5. MMW measurement in frequency domain using ZVA67, QPW-50662330-C1, and Rotagrip (precision cross table) for antenna positioning (August 2014). The aim of this measurement was the same as in M3 but for MMW band (the spatial grid used for antenna positioning was set to 4 mm).

M4. WiFi 802.11p channel measurement in frequency domain (August 2014). Due to large popularity of the Wireless Access for the Vehicular Environment (WAVE) technology in the 5.8 GHz band we carried out a few measurements for the WAVE channel analysis.

M3. UWB measurement in frequency domain using VNA E5071C and spatial grid (10 x 10 spatial positions distant 3 cm each other) for antenna positioning (May 2014). The aim of the measurement was to analyze the spatial stationarity of the intra-vehicle channel.

M2. UWB measurement in time domain (March 2014). This measurement could be carried out thanks to the generous support from Tektronix represented by the company Testovací Technika s.r.o. which lend us Arbitrary Waveform Generator AWG70002A (for generation of short UWB pulses).

M1. MMW measurement in frequency domain (February 2014) based on ZVA67 and Quinstar power amplifier QPW-50662330-C1 (purchased from grant funds).

In accordance with the project activities schedule (see Gantt chart in the project application) in 2014 we have worked in the four work packages
