Joint Decoding Schemes for Wireless Relay Networks with Multiple Antennas Cooperative relaying is gaining a significant attention in that intermediate relay nodes assist the source nodes in order to enhance the overall network efficiency In wireless relay network, the relay node forwards the data received from the sources to the destination In this proposal, we plan to design optimal decoding schemes for three models of the wireless relay network that is composed single sources, single relay, and single destination The three models differ in number of antennas available at each node In order to get the optimal performance and reduce the complexity of the decoding scheme, three schemes are jointly used to retrieve the data sent from the source These three schemes are maximum a posterior decoding, Alamouti combining, and maximum ratio combining We plan to derive a closed form expression for upper bound on the word error probability The closed form expression of the upper bound can be used to determine the optimal position of the relay node in each case
