The quality signal in a wireless transmission occasionally suffers from severe bad channel quality due to effects like fading caused by multi-path propagation. Diversity is one of the methods that used to reduce such effect whereby different samples of the same signal are transferred over essentially independent channels. Cooperative wireless communication it resolves this problem by transmitting a message to a destination with the assistance of a relay. Upon receiving the message from the transmission source, the relay retransmits the message to the destination.
