Performance Enhancement of Wireless Datalink Modem Using Channel Coding
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.
