Abstract

The reliable transmission of multimedia information that is coded through highly compression efficient encoders is a challenging task. This article presents the iterative convergence performance of IrRegular Convolutional Codes (IRCCs) with the aid of the multidimensional Sphere Packing (SP) modulation assisted Differential Space Time Spreading Codes (IRCC-SP-DSTS) scheme for the transmission of H.264/Advanced Video Coding (AVC) compressed video coded stream. In this article, three different regular and irregular error protection schemes are presented. In the presented Regular Error Protection (REP) scheme, all of the partitions of the video sequence are regular error protected with a rate of 3/4 IRCC. In Irregular Error Protection scheme-1 (IREP-1) the H.264/AVC partitions are prioritized as A, B & C, respectively. Whereas, in Irregular Error Protection scheme-2 (IREP-2), the H.264/AVC partitions are prioritized as B, A, and C, respectively. The performance of the iterative paradigm of an inner IRCC and outer Rate-1 Precoder is analyzed by the EXtrinsic Information Transfer (EXIT) Chart and the Quality of Experience (QoE) performance of the proposed mechanism is evaluated using the Bit Error Rate (BER) metric and Peak Signal to Noise Ratio (PSNR)-based objective quality metric. More specifically, it is concluded that the proposed IREP-2 scheme exhibits a gain of 1 dB with reference to the IREP-1 and gain of 0.6 dB with reference to the REP scheme over the PSNR degradation of 1 dB.

Highlights

The advent of diverse video applications and services increases the need for a highly efficient network, providing massive connectivity, reliable, and low latency communication, along with higher channel capacity
The results were obtained while transmitting the H.264/Advanced Video Coding (AVC) coded “KIYO” video phone sequence using Regular Error Protection (REP), Irregular Error Protection scheme-1 (IREP-1), and Irregular Error Protection scheme-2 (IREP-2) error protected schemes
From the EXtrinsic Information Transfer (EXIT) chart analysis of the REP, Irregular Error Protection (IREP)-1, and IREP-2 error-protected schemes, it was observed that the iterative Multi-code IrRegular Convolutional Codes (IRCCs) coding paradigm in combination with Unity Rate Coder (URC) results in better convergence behavior when compared to the using Uni-code IRCC employed in the REP scheme

Summary

Introduction

The advent of diverse video applications and services increases the need for a highly efficient network, providing massive connectivity, reliable, and low latency communication, along with higher channel capacity. The future network has to be a combination of different technologies and intend to be efficiently managed, optimized, and integrated for diverse applications and networking scenarios, extending the battery lifetime of a low powered devices as well as providing a very fast and high data rate connectivity to the user with higher mobility [1]. Challenges still exist in providing higher data rates, portability, mobility, quality of service, security to end-user, and higher connectivity in wireless communication [2]. In the wired communication channel, reducing the error rate from 10−2 to 10−3 may be obtained by increasing 1 or 2 dB SNR. An issue arises as to transmitting multiple copies with minimum transmitting power, bandwidth, and decoding complexity
