Tandem source-channel coding is proven to be optimal by Shannon given unlimited
delay and complexity in the coders. Under low delay and low complexity constraints,
joint source-channel coding may achieve better performance. Although digital joint
source-channel coding has shown a noticeable gain in terms of reconstructed signal
quality, coding delay, and complexity, it suffers from the leveling-off effect. However,
analog systems do not suffer from the leveling-off effect. In this thesis, we investigate
the advantage of analog systems based on the Shannon-Kotel'nikov approach and
