Experimental Evaluation for Relaying System Allowing Intralink Error

Experimental Evaluation for Relaying System Allowing Intralink Error This paper presents an experimental performance evaluation for relaying system allowing intralink error, which is commonly avoided. 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-softwareradio-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.
