Abstract
In this paper, we propose QAPM(Quadrature Amplitude Position Modulation) modulation scheme for improving power efficiency and we compare existing PSSK(Phase Silence Shift Keying) and QAPM. An existing PSSK Modulation is extension from PSK modulation technique. The conventional PSSK modulation technique can be regarded as an extension from PSK modulation. And this PSSK has better power efficiency than PSK modulation. The Bandwidth efficiency of PSSK is half than PSK, but improved BER(Bit Error Rate) performance. A propose QAPM scheme is build on QAM. And BER performance of QAPM is better than PSSK because BER performance of QAM is better than PSK. In this paper, we compare PSSK and QAPM regard to bit error rate and throughput.
