Abstract-It is known that the frame error rate of turbo codes on quasi-static fading channels can be accurately approximated using the convergence threshold of the corresponding iterative decoder. This paper considers quasi-static fading channels and demonstrates that non-iterative schemes can also be characterized by a similar threshold based on which their frame error rate can be readily estimated. In particular, we show that this threshold is a function of the probability of successful frame detection in additive white Gaussian noise, normalized by the squared instantaneous signal-to-noise ratio. We apply our approach to uncoded binary phase shift keying, convolutional coding and turbo coding and demonstrate that the approximated frame error rate is within 0.4 dB of the simulation results. Finally, we introduce performance evaluation plots to explore the impact of the frame size on the performance of the schemes under investigation.

“…Many of these studies are concerned with the optimization of the effective throughput of the channel, without considering the impact of source and channel coding on the transport delay and delay jitter. The delay performance of hybrid ARQ schemes has been studied in [21,22] independently of the video content (i.e., without regard to source coding). Most studies on joint source/channel coding address the problem from an information theoretic point of view, and did not account for network performance and protocol issues, including packetization and retransmissions.…”

Video streaming over wireless channels is challenged with the time-varying nature of the underlying channels and the stringent requirements of video applications. In particular, video streaming has strict requirements on bandwidth, delay, and loss rate while wireless channels are dynamic and error-prone by nature. In this article, we propose a novel multilevel adaptive scheme that is designed to mitigate the challenges facing video streaming over unreliable channels. This is done while preventing potential playback discontinuities and guaranteeing a graceful degradation of the rendered video quality. Scalable video coding, adaptive modulation, and adaptive channel coding are integrated to achieve the objectives of the proposed scheme. If adaptive modulation and channel coding are not enough to guarantee the on-time delivery of decodable video frames, we adopt scalable coding. Simulation results show that the proposed adaptive scheme achieves an improvement of about 2.5 dB in the peak signal-to-noise ratio over a nonadaptive one. In addition, the proposed scheme reduces the number of starvation instances by 50 and 90% in the cases of Stop-and-Wait and Go-Back-N automatic repeat requests, respectively.
