By utilizing the main advantages of orthonormalization and power conservation from hilbert transformation, it is found that bit error rate is close to that of dcsk system, but transmission speed is one time higher than that of dcsk system, and the system ' s output variance is effectively reduced
基於qpsk的思想，引入qcsk調制方式，利用hilbert變換對正交且能量守恆的特性，有效減小了系統輸出的方差，較dcsk系統，傳輸速率提高一倍，系統誤比特率與dcsk系統相近。 -
