It provides alternative means of Equal Error Protection (EEP) to the transmitted bits without increasing the bandwidth. Hierarchical Quadrature Amplitude Modulation (HQAM), a modification of QAM, provides Unequal Error Protection (UEP) to the transmitted bits for increasing the protection to the sensitive and non-sensitive bits and is also efficient in power and bandwidth. This paper presents an analysis and simulation of HQAM in order to bring out its merits over QAM. The simulation is carried out using MATLAB & Simulink for different values of modulation parameter. A Simulink-based simulation system is designed for the transmission of gray image as test image over AWGN wireless channel. 2012-06-05T04:48:31Z 2012-06-05T04:48:31Z 2011-09-20 Working Paper p. 227-232 978-076954562-2 http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6076361 http://hdl.handle.net/123456789/19687 en Proceedings of the 3rd International Conference on Computational Intelligence, Modelling and Simulation (CIMSim) 2011 Institute of Electrical and Electronics Engineers (IEEE)
