Performance analysis of differential phase modulation for HF communication

Data transmission using HF spectrum (3-30 MHz) is widely used due to its ability in providing long distance communications at low cost. Due to multipath fading problems in HF channels, the maximum symbol rate of data transmission is limited to 100 baud per second. Differential multiple phase modulat...
