Abstract [en]

Hard-limited quadrature pulse-overlapping modulation (QPOM) techniques have a constant envelope, good spectral properties and good performance especially in fading channels. These modulation techniques are suitable to applications using nonlinear or saturated power amplifiers to obtain high power and bandwidth efficiencies. A technique to combine convolutional codes and QPOM schemes to further improve its performance in fading channels is introduced and evaluated. At first, the QPOM scheme is decomposed into an encoder followed by a memoryless modulator. Then, the binary convolutional encoder is concatenated to the QPOM encoder and considered as one entity to be optimized. Performance of the coded QPOM scheme is analyzed and compared to uncoded QPOM and coded QPSK schemes
