Abstract :
In this paper, we analyze a QAPM (Quadrature Amplitude Position Modulation) scheme for improving power efficiency in multi-path channel. An existing PSSK (Phase Silence Shift keying) modulation is a simple extension from PSK modulation technique. This 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 is half than PSK, but BER performance is improved. A proposed QAPM scheme is built on QAM. And BER performance of QAPM is better than PSSK because BER performance of QAM is better than PSK. In this paper, we find the BER performance closed form of QAPM modulation. Also, we compare QAPM and PSSK regard to BER performance and throughput.
