Performance of M-ary Orthogonal Continuous Phase FSK (Frequency Shift Keying) for a Trans-Ionospheric Time-Varying Frequency-Selective Channel

摘要

M-ary Orthogonal continuous Phase FSK modulation can significantly improve severe frequency-selective channel Bit Error Rate over conventional modulation techniques. This modulation technique has the potential to enhance the performance of channel equalizers and error correction and coders in a selective channel.
