Optimized cooperative diversity for a three-node decode-and-forward relay channel

Due to space limitation, providing space diversity at mobile stations such as handsets or personal digital assistants (PDA) is problematic in mobile ad hoc networks (MANET). Recent studies, however, have shown that extraordinary diversity advantages can be obtained from a relay node in the proximity...
