In this paper, we present an empirical verification of the method of determining the Doppler spectrum (DS) from the power angular spectrum (PAS). Measurements were made for the frequency of 3.5 GHz, under non-line-of-sight conditions in suburban areas characteristic of a university campus. In the static scenario, the measured PAS was the basis for...

Context 1
... part of test-bed was equipped with an omnidirectional antenna (see Fig. 3). In the static scenario, the receiving part was also stationary and the RX was equipped with a directional antenna mounted on the turn table (see Fig. 4). In the mobile scenario, the RX was equipped with an omnidirectional antenna that was mounted on the vehicle roof (see Fig. 5). Figure 3 shows a block diagram of the transmitting testbed part. The SMF100A signal generator by Rohde & Schwarz (R&S) generated a 3.5 GHz signal, which was additionally stabilized with an external rubidium standard. The generator was connected to the input of the transmitting antenna OMNI A0105 operating at the frequency of 3.5 GHz. ...
Context 2
... block diagram of the mobile receiving part of the testbed is shown in Fig. 5. The R&S ESMD measurement RX with an active receiving antenna, OMNI A0107, connected to its input, was used to build the mobile receiving part of the test-bed. In this case, a rubidium standard was also used as an external reference signal source to stabilize the measurement ...
