Low-density parity-check convolutional codes offer

the same good error-correcting performance as low-density

parity-check block codes while having the ability to encode and

decode arbitrary lengths of data. This makes these codes well

suited to certain applications, such as forward error control on

packet switching networks.

In this paper we propose a decoder architecture for low-density

parity-check convolutional codes with very large memories. These

codes have very good error correcting properties and as such

may be applicable in space and satellite communication systems.

We discuss a realization of this architecture implemented on a

eld-programmable gate array
