Apparatus and method for increasing channel capacity of a mobile communication system using HPSK

The mixed phase-shift keying HPSK modulating method is used to increase the capacitor channel in a mobile communication system and device. The method comprises: Walshe code control unit, a inspection are from the first Walshe coding unit and second Walshe Walshe code of sequence code output unit; Walshe rotor, is used for generating multiple a complex functions and output them; And the control unit, a conductive according to sequence code for choosing from the first Walshe coding unit and second Walshe output unit Walshe from the de-repeated complex functions according Walshe rotor and. The method may use the Walshe coding, and then the backward for capacitor.
