We consider the doped-accumulator-assisted distributed turbo code (ACC-DTC), where simple coding and decoding is involved due to the use of only memory-one convolutional codes. Our main goal is to experimentally verify the diversity order of the ACC-DTC by obtaining BER and FER as function of signal-to-noise ratio (SNR). The measurement scenario takes place both indoor (house type environment) and outdoor (garden type environment) in a suburban home in Indonesia by using software defined radio (SDR). In this experiment, we use LabVIEW and NI USRP-2920. As complement of this paper, a”real-time” demo application using only two universal-software-radio-platforms (USRP), to evaluate the possibility for further development of the ACC-DTC into real applications, is made by adding energy detector to trim non-packet signal and by simplifying the ACC-DTCs computational complexity. We found that even though very simple memory-one convolutional codes are conducted, full diversity order two is achieved in the real-field experiments.[/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]BER and FER,Distributed codes,Diversity order,Relay system,Space diversity,USRP[/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]BER and FER,Distributed code,Diversity order,Iterative decoding,Relay system,SDR,Space diversity,USRP[/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]This research has been conducted under the Grant-in-aid for Scientific Research KIBAN KENKYU (B) No. 25289113 and in part conducted under the EU FP7 RESCUE No. 619555.[/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][/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]
