PROBLEM TO BE SOLVED: To provide a multi-value modulation/demodulation method that enables a plurality of power amplifiers to operate in a saturation region where high efficiency is possible, can reduce the amount of power consumption, and allows economical achievement of construction for a ...
Multilevel modulation methods are basically classified based on carrier‐based modulation (CBM) and space vector modulation (SVM). Both of these modulations belong to the same family of pulse﹚idth modulation. SVM is heavily dependent on the computational calculations; hence, there is no need to ...

We report on-chip all-optical wavelength conversion of multicarrier multilevel modulation signals in a silicon waveguide. Using orthogonal frequency-division multiplexing (OFDM) combined with advanced multilevel quadrature amplitude modulation (QAM) signals (i.e., OFDM m-QAM), we experimentally demonstr...
This paper presents bit splitting methods to apply multilevel modulation to iterative codes such as turbo code, low density parity check code and turbo product code. Log-likelihood ratio method splits multilevel symbols to soft decision symbols using the received in-phase and quadrature component ba...
Probability Density Function of Reliability Metrics in BICM with Arbitrary Modulation: Closed-form through Algorithmic Approach In the popular bit-interleaved coded modulation (BICM) the output of the channel encoder and the input of the modulator are separated by a bit-level interl...
