A New Space-Time Cooperative Diversity Relaying Strategy with Assistant and Management Terminals
Eun-Ki Kim, Young-Ju Kim, Insung Lee · 2007
A new space-time cooperative communication relaying strategy with assistant or management terminals is proposed in multi-hop wireless communication systems. More than one relaying terminals are included in one cooperative group to share the state information such as frame error rate and channel information. Among the cooperative group, the best ones are selected to send bit information using space-time codes. An implementation for the proposed scheme is also presented using a TDMA cooperative protocol. Receive signal to transmit signal ratio() and computer simulation show the strategy outperform the conventional cooperative system.
