Rateless and rateless unequal error protection codes for Gaussian channels
In this thesis we examine two different rateless codes and create a rateless unequal error protection code, all for the additive white Gaussian noise (AWGN) channel. The two rateless codes are examined through both analysis and simulation with the hope of developing a better understanding of how …

A comparative analysis of physical-layer rateless coding architectures
An analysis of rateless codes implemented at the physical layer is developed. Our model takes into account two aspects of practical communication system design that are abstracted away in many existing works on the subject. In particular, our model assumes that : (1) practical error detection …

A Novel Approach for Implementing Worldwide Interoperability for Microwave Access for Video Surveillance
… of the lower layers, this thesis employs a rateless code instead of transport layer redundancy in the application layer. Moreover, this thesis proposes post-decoding error concealment techniques as the last means to overcome packet loss. To evaluate the performances of the proposed methods, …

Near-capacity fixed-rate and rateless channel code constructions
Fixed-rate and rateless channel code constructions are designed for satisfying conflicting design tradeoffs, leading to codes that benefit from practical implementations, whilst offering a good bit error ratio (BER) and block error ratio (BLER) performance. More explicitly, two novel low-density …

Closed-loop multiple antenna aided wireless communications using limited feedback
… rapidly fading channels. A pilot symbol assisted rateless code is also proposed in Chapter 3, which exploits the available pilot symbols not only for channel estimation but also for channel<br/>decoding. Furthermore, an Extrinsic Information Transfer (EXIT) Chart optimised Channel Impulse Response …
