Abstract(in English) | In this paper, we improved the degraded performance of BER caused by the increase of maximum Doppler frequency on mobile radio communication systems. When the mobile station is moving fast, then maximum Doppler frequency increases; as a result channel estimation will be failed. So, here we apply punctured Turbo Codes, and replace some parity bits of Turbo Codes with Pilot symbols. In this scheme, performance improvement is realized without decrease of data rate. Thus we get better performance of BER, by decreasing the interval of Pilot symbols and robustness for puncturing on Turbo Codes. We conducted computer simulation, in case maximum Doppler frequency is 5Hz |
