Abstract
This paper presents an overview of modern types of signal manipulation such as hierarchical quadrature amplitude modulation (HQAM), circular quadrature amplitude modulation (CQAM) and parametric quadrature amplitude modulation (θ-QAM). Then follows the modeling of the above-mentioned types of modulations and quadrature amplitude modulation (QAM) using the MATLAB programming language. To compare the four selected types of modulation two types of modulation order are used: 16 and 64. To evaluate the effectiveness of using one or another type of modulation a communication channel was modeled to which additive white Gaussian noise (AWGN), Doppler frequency distortion and inaccurate frame synchronization were added.
