  Luby Transform (LT) codes are a class of fountain codes that have proved to
perform very efficiently over the erasure channel. These codes are rateless in
the sense that an infinite stream of encoded symbols can be generated on the
fly. Furthermore, every encoded symbol is information additive and can
contribute in the decoding process. An important application of fountain codes
which is being considered is the delivery of content over mobile wireless
channels. Fountain codes have low computational complexity and fast encoding
and decoding algorithms which makes them attractive for real time applications
such as streaming video over wireless channels. L T codes are known to perform
close to capacity on the binary erasure channel and it is envisaged that they
would have good performance on other channels such as mobile communication
channels and satellite links. This paper considers the development of a
test-bed to study the performance of fountain codes over such channels. The
performance of LT codes on the binary symmetric channel and Additive White
Gaussian Noise (A WGN) Channel is presented as examples of the testbed usage.
