In this paper, performance analysis of joint source-channel coding techniques for error-resilient transmission of three dimensional (3D) models are presented. In particular, packet based transmission scenarios are analyzed. The packet loss resilient methods are classified into two groups according to progressive compression schemes employed: Compressed Progressive Meshes (CPM) based methods and wavelet based methods. In the first group, layers of CPM algorithm are protected unequally by Forward Error Correction (FEC) using Reed Solomon (RS) codes. In the second group, embedded bitstream obtained from wavelet based coding is protected unequally with FEC as well. Both groups of methods are scalable with respect to both channel bandwidth and packet loss rate, i.e. they try to optimize FEC assignments with respect to channel bandwidth and packet loss rates (PLR). In-depth analysis of these techniques are carried out in terms of complexity, robustness to losses and compression efficiency. Experimental results show that wavelet based methods achieve considerably better quality compared to CPM based methods.

Packet loss resilient transmission of 3D models Bici, M. Oguz; Norkin, Andrey; Akar, Gözde (2007-09-19) This paper presents an efficient joint source-channel coding scheme based on forward error correction (FEC) for three dimensional (3D) models. The system employs a wavelet based zero-tree 3D mesh coder based on Progressive Geometry Compression (PGC). Reed-Solomon (RS) codes are applied to the embedded output bitstream to add resiliency to packet losses. Two-state Markovian channel model is employed to model packet losses. The proposed method applies approximately optimal and unequal FEC across packets. Ther...
Optimized Transmission of 3D Video over DVB-H Channel Bugdayci, Done; Akar, Gözde; Gotchev, Atanas (2012-01-17) In this paper, we present a complete framework of an end-to-end error resilient transmission of 3D video over DVB-H and provide an analysis of transmission parameters. We perform the analysis for various layering, protection strategy and prediction structure using different contents and different channel conditions.
Autoencoder-Based Error Correction Coding for One-Bit Quantization Balevi, Eren; Andrews, Jeffrey G. (2020-06-01) This paper proposes a novel deep learning-based error correction coding scheme for AWGN channels under the constraint of one-bit quantization in receivers. Specifically, it is first shown that the optimum error correction code that minimizes the probability of bit error can be obtained by perfectly training a special autoencoder, in which "perfectly" refers to converging the global minima. However, perfect training is not possible in most cases. To approach the performance of a perfectly trained autoencoder...
Non-Binary LDPC Codes for Magnetic Recording Channels: Error Floor Analysis and Optimized Code Design Hareedy, Ahmed; Amiri, Behzad; Galbraith, Rick; Dolecek, Lara (2016-08-01) © 2016 IEEE.In this paper, we provide a comprehensive analysis of the error floor along with code optimization guidelines for structured and regular non-binary low-density parity-check (NB-LDPC) codes in magnetic recording (MR) applications. While the topic of the error floor performance of binary LDPC codes over additive white Gaussian noise (AWGN) channels has recently received considerable attention, very little is known about the error floor performance of NB-LDPC codes over other types of channels, des...
Nonlinear 3D Modeling and Vibration Analysis of Horizontal Drum Type Washing Machines Baykal, Cem; Ciğeroğlu, Ender; Yazıcıoğlu, Yiğit (2020-01-01) In this study, a nonlinear 3-D mathematical model for horizontal drum type washing machines is developed considering rotating unbalance type excitation. Nonlinear differential equations of motion are converted into a set of nonlinear algebraic equations by using Harmonic Balance Method (HBM). The resulting nonlinear algebraic equations are solved by using Newton’s method with arc-length continuation. Several case studies are performed in order to observe the effects of orientation angles of springs and damp...
