Abstract/Resumo
Magnitude modulation (MM) techniques applied to single carrier (SC) transmissions provide the potential for gains in power efficiency by reducing the signal's peak-to-average power ratio, allowing efficient power amplification at the transmitter's side. This paper presents an accurate analytical model to measure the intrinsic symbol error rate (SER) due to MM distortion for systems employing high-order constellations and proposes a new feedback based soft-iterative magnitude demodulation (SiMD) scheme for the receiver with proper estimation of the MM factors used in transmission in order to compensate for the MM distortion introduced at the transmitter. It is shown that this technique allows the design of MM highly power efficient SC transceivers with high spectral efficiency.
