摘要：
An OFDM baseband signal that has undergone a synchronization carrier modulation or a differential carrier modulation is inputted to a complex signal converter for nonlinear distortion equalization so as to be converted according to the N-th order function conversion characteristics (N>1). Then, nonlinear distortion in the OFDM baseband signal is compensated for. At this time, the following is used as a conversion equation: y(n)=x(n)+Σam(n)xm(n)(m>1) wherein the values of the input signal, the output signal and the coefficient for m-th order distortion equalization at time n are, respectively, x(n), y(n) and am(n).
