In this paper, the authors are concerned with evaluating the performance of Differential Space Time Block Coding (DSTBC) over Very High Frequency (VHF) aeronautical communication channels (i.e. air-to-ground). Differential Phase Shift Key (DPSK) is one of the differential transmission schemes that transmit information without full Channel State Information (CSI) at the receiver. There are two main problems that degrade the performance of the communication over this channel, multipath fading which is a common problem in any wireless channel and Doppler shifts which result from aircraft speeds.
