Long Term Evolution (LTE) is a 4G wireless broadband technology developed by Third Generation Partnership Project (3GPP), an industry trade group. 3GPP has been centered on enhancing LTE radio standards to improve the performance of wireless communications link, receive diversity has been proposed by the 3GPP within mode 1 of transmission in the LTE standard. In this paper, we focus on the HAPS-LTE downlink system performance evaluation with optimum receive spatial diversity and has channel side information known at the receiver (CSIR) for different scenarios. Simulation results show that, HAPS channel characteristics such as elevation angle, user mobility, and channel bandwidth greatly affect the performance of the proposed system. It is also shown that, maximal-ratio combining (MRC) diversity algorithm is able to improve the system performance in bad channel conditions.[/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]Channel side information,Diversity,HAPS,High altitude platform station,Maximal ratio combining diversities,Rician channels,Third generation partnership project (3GPP),Wireless communications[/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]Diversity,HAPS,LTE,MRC,Rician channel[/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/ICWT.2018.8527779[/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]
