Measurement, Modeling, and Synchronization for the Mobile Channel

Wideband measurements of the mobile-to-mobile
channel are necessary for proper design and
certification testing of mobile-to-mobile
communications systems. A complete measurement
implies that the Doppler and delay characteristics
are measured jointly. The main topic presented is
the development of channel models for specific
scenarios from data obtained in measurement
campaigns. For this purpose we developed a channel
sounding system including a novel combined waveform.
In order to quantify and qualify either the recorded
channel or the proposed generated channel, we
developed a simulation test-bed that includes all
the characteristics of the DSRC standard. The
resulting channel models needed to comply with the
specifications required by hardware channel
emulators or software channel simulators. From the
obtained models, we selected one to be included in
the IEEE 802.11p standard certification test. To
further aid in the development of software radio
based receivers, we also developed an OFDM
synchronization algorithm to analyze and compensate
synchronization errors produced by inaccessible
system clocks.
