Multi-Input Multi-Output Deletion Channel
Cataloged from PDF version of article.We describe a new channel model suitable in certain
applications, namely the multi-input multi-output (MIMO) deletion
channel. This channel models the scenarios where multiple
transmitters and receivers suffering from synchronization errors
are employed. We then consider a coding scheme over such
channels based on a serial concatenation of a low-density parity
check (LDPC) code, a marker code and a layered space-time
code. We design two detectors operating at the bit level which
jointly achieve synchronization for the deletion channel (with the
help of the marker code) and detection for the MIMO channel.
Utilizing the proposed detector together with an LDPC code
with powerful error-correction capabilities, we demonstrate that
reliable transmission over a MIMO deletion channel is feasible
