Abstract
the source data into a plurality of pairs of in-phase (I) and quadrature phase (Q) data channel modulation signal method comprising the following steps: 1) coding the source data to generate a data part and a control part b) generating a spreading code channel allocated to such that consecutive two pairs of I and Q data and corresponding to two points located on same point or one zero to two points on the phase domain phase symmetrical; and c) respectively to extend to the control part and the data part by said spreading code. the method can reduce the peak average power ratio of mobile communication system so as to improve the power efficiency of the mobile platform.
