Abstract :
In this paper, we analyze performance of low power consumption modulation scheme such as Phase Shift Position Modulation(PSPM), Phase Silence Shift Keying(PSSK) and Quadrature Amplitude Position Modulation(QAPM) using OFDM transmission in AWGN channel. A PSPM, PSSK and QAPM modulation scheme are decrease in bandwidth efficiency but improved power efficiency than existing PSK and QAM. These modulation schemes can achieve power efficiency because every symbol of modulations has a zero-envelope period like PPM techniques. The OFDM system is high bandwidth efficiency than single carrier system. In this paper, we compare PSPM, PSSK and QAPM modulation using OFDM transmission regard to BER performance, throughput and PAPR.
