The wideband channel has been analyzed at the University of Gävle by using millimeter-wave (mm-Wave) frequency for improving the fifth-generation (5G) in Radio-frequency (RF) characterization. The proposed mm-Wave frequency is 24GHz, which is carried out from measurement testbed at the Robotics Lab. To explore the channel behaviors of the ISM band and mobile radio, three typically environments have been created inside of the Robotics Lab at the University of Gävle in which are Higher reflection (HR), natural reflection (NR), and Ultra reflection (UR). The relative motion of the transmitter (Tx) is carried out by adjoining the omnidirectional antenna to a KUKA robot's arm inside the Robotics lab at the University of Gävle, Sweden. The radio channel behavior is observed at different circumstances with two different movements of KUKA’s arm e.g., higher speed (2m/s) and slower speed (1m/s) for the Line of sight (LOS) and Non-Line of sight (NLOS) condition. We then achieve the time-varying power delay profile (PDP) and frequency-varying Doppler spectral density (DSD) from scattering components of the experiment environment. The Wide-band channel characteristics have been based on the (PDP) and (DSD), we analyze the root-mean-square of the (RMS) delay spread, RMS Doppler spread, Coherence time, Coherence bandwidth, and mean delay, Doppler shift from 24 different scenarios for behaviors of the mobile radio channels and indoor wireless application. / <p>Actually, My thesis title is '' A Study of Multipath Propagation and Doppler Effect at 24GHz ISM band''. I have generated mm-wave frequency from my testbed which is 24GHz. For better analysis, i was designed and created a Multipath environment inside of the Robotics Lab at University of Gävle, I also used KUKA Robot and designed two diffrient motion for the Transmitter,such as ''C'' type and '' inverse ''type .</p>
