Estimation is based on experimental data which was collected from an object floating above the ground and carrying transmitter apparatus to perform as a HAPs. This experiment is intended to study multipath channel behaviour represented by K value for a wireless communication using HAPs. We use moment-based method estimator to characterize HAPs-channel in a wide interval of elevation angle. Secondly, the performance of WiMAX (IEEE802.16e) high speed transmission is simulated over the predicted HAPs channel. It is also shown how Doppler effect and K factor which is governed by elevation angle can contribute to the performance. We found that WiMAX services, which require high level requirement, fail to achieve an acceptable performance over HAPs channel if the elevation angle is lower than 40 degrees. © 2008 IEEE.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Communication channels,Doppler,Elevation angle,Experimental data,HAPs,High-altitude platforms,High-speed transmission,IEEE 802.16,International conferences,K factor,K values,Mobile communications,Multi-path channels,Performance evaluation,Rice factor,Ricean channel,WiMAX,Wireless channels,Wireless communication[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]HAPs,K factor,Ricean channel,WiMAX[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ICWMC.2008.20[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
