Abstract
The transmission of large data streams over error-prone channels as e.g. in multimedia applications
is inherently linked to long transmission delays if automatic repeat
request schemes are used.
As this article
will show, the delay can be reasonably traded against
residual bit errors if a short transmission time has highest
priority.
The dependency of the delay on two important factors, packet length
and channel bit error rate, is determined to be non-linear and
strictly monotonously growing.
Furthermore, transmission behavior and properties of a plain binary symmetric
channel and one with additional repeat request technique are simulated and
compared to previous research.
The simulations finally lead to a redefinition of the formula for the estimation of the
residual bit error rate of a non-transparent
channel.
