A notable form of communication systems is voice communication, which is needed in various areas including the military. A widely used type of military communication systems is the tactical communication. Indonesia is currently developing digital communication systems to meet national military demand, to communicate using multichannel high frequency (HF) band. Each channel has a limited bandwidth of 40 kHz. This bandwidth limit inquires a compression/decompression routine from the digital voice acquisition coder to lower the digital voice bit rate. Low bit rate speech coding and modulation with a narrow bandwidth is the goal of this project. The algorithms for compression and modulation are implemented in C with PC to model the processor. Reconstructed voice from the baseband processor prototype is tested subjectively by taking sample respondents to conduct mean opinion scoring (MOS) method. The MOS perception testing score gives an average score ranging from 3 (sufficiently decent with tolerable minor disturbances) to 4 (good). © 2013 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]basebandprocessor,Bit rates,mean opinion scoring,Software-defined radios,Tactical 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]bandwidth,basebandprocessor,bit rate,compression and decompression,mean opinion scoring,modulation and demodulation,software-defined radio,Tactical 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=”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/ICTSS.2013.6588090[/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]
