Description
During the last 25 years, most of the communication systems have been converted to purely digital technology, although the transmitted content mostly is analog by nature. The principal advantages of digital communication are compression by source encoding, bit error protection by channel coding and robust transmission over noisy channels by appropriate modulation. Digital systems are usually designed for worst case channel conditions. However, often the channel quality is much better, which is not reflected in an improved end-to-end transmission quality due to inevitable quantization noise produced by the source encoder.
In this thesis, the focus is set on systems which:
are not purely digital anymore
benefit from increasing channel qualities and
avoid the saturation effect using discrete-time, continuous-amplitude techniques.
In the first part, purely analog, i.e., discrete-time and continuous-amplitude transmission systems are considered with line
