Method and system for generating higher order modulations with QPSK modulators. A complex sequence of binary digits is input to QPSK modulators. The binary digits are mapped to constellation points and multiplied with weighting coefficient. Constellation points of higher order modulation are mapped to inputs of the QPSK modulator, and, after modulation QPSK symbols are summed to compose symbols of higher order modulation.
