ABSTRACT In this paper, a low-complexity unequal error protection (UEP) of H.264/AVC coded video using adaptive hierarchical quadrature amplitude modulation (HQAM), which takes into consideration the non-uniformly distributed importance of intracoded frame (I-frame) and predictive coded frame (P-frame) is proposed. Simulation results show that in terms of average peak signal-to-noise ratio (average PSNR), our proposed (EEP) scheme outperforms the equal error protection (EEP) by up to 5 dB

    ABSTRACT: We investigate the rate-compatible punctured convolutional (RCPC) codes concatenated with hierarchical QAM for designing a cross-layer unequal error protection scheme for H.264 coded sequences. We first divide the H.264 encoded video slices into three priority classes based on their relative importance. We investigate the system constraints and propose an optimization formulation to compute the optimal parameters of the proposed system for the given source significance information. An upper bound to the significance-weighted bit error rate in the proposed system is derived as a function of system parameters, including the code rate and geometry of the constellation. An example is given with design rules for H.264 video communications and 3.5-4 dB PSNR improvement over existing RCPC based techniques for AWGN wireless channels is shown through simulations.

    ABSTRACT: The research on three-dimensional (3-D) video transmission over wireless networks has gained rapid growth in the last view years and poses more challenges than the conventional two-dimensional (2-D) video. In color plus depth representation, the 3-D video is synthesized from color and depth map and the reconstructed quality is highly affected by color information rather than the depth one. In this paper, an unequal error protection (UEP) scheme based on hierarchical quadrature amplitude modulation (HQAM) for 3-D video transmission is proposed. The proposed scheme exploits unique characteristics of the color plus depth map stereoscopic video. The UEP scheme assigns more protection to the color sequence than the depth map so as to achieve high quality 3-D video. Simulation results demonstrate that the proposed UEP scheme outperforms the conventional equal error protection (EEP) schemes by up to 5 dB in terms of the received left and right views quality.

    ABSTRACT: Asymmetric modulation techniques like Quadrature Amplitude Modulation system is one of the key techniques in building a broadband mobile communication network because of increasing shortage of wireless communication channels. 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.
