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.
