| وصف الكتاب | 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. |
