High efficiency modulation scheme with ternary coding for satellite transmissions

For high bandwidth efficiency and better performance of the satellite communication, a novel modulation and demodulation scheme named Ternary Coded Pulse Shape Modulation (TC-PSM) is proposed. By analyzing the character of high band satellite channels and the features of existing modulation schemes, TC-PSM scheme is presented. The performance of the TC-PSM scheme is analyzed theoretically and the simulation result is presented. The analysis shows that the proposed method can increase the date rate to bandwidth ratio with a little grow of the cost of the signal to noise ratio and the normalized PAPR is lower than that of NOTDM. The proposed method is suitable for the satellite communication system.
