| Abstract | ||||
| This paper is concerned with evaluating the performance of M-ary differential phase shift keying (M-ary DPSK) modulation schemes over (very high frequency) VHF aeronautical channel (air-to-ground communication channel). The paper investigated the analytical bit error rate (BER) performance of binary differential phase shift keying (BDPSK) over aeronautical channel for flight scenarios: En -route, Arriving, Taxiing, and parking. By using the published measurement parameters, the analytical results are verified through modeling and computer simulation. The BER results show that multipath fading and Doppler shifts in the VHF aeronautical channel degrade the performance of M -ary DPSK modulation schemes over the channel. In order to combat fading and improve the BER performance of this channel, the paper proposed computer simulation of the performance of differential space time block coding (DSTBC) using two antennas at the transmitter and one antenna at the receiver. | ||||
