In this paper the model having D8PSK modulation applied by channel coding of Convolution Turbo Code (CTC) was designed and analyzed to improve the performances of wireless communication system for data link between ground equipment and aircraft. The suggested modem was differential 8PSK modulation system and channel coding of Convolution Turbo Code (CTC) system, and TDMA system was used for transmission. The hardware was embodied for the test and done by using 2 FPGA’s and DSP. The function of FPGA has the one of modulation and demodulation of signal, acquisition and maintaining of TDMA synchronization and generating timing signal. As the test results, it was recognized that the transmission rate can be maintained though the code rate is increased based on 28.8 Kbps and the performance of SNR gets 15dB when BER performance criteria is 10-6. And, it was recognized that the performance of BLER satisfies 10-4 based on BER 10-6. And, it was also recognized that the performance of SNB was improved by 4dB comparing with the case which channel coding was not used from the test results.
