摘要：
Differential unitary space time modulation (USTM) is identified as one of the best non-coherent technique for future 5th generation mobile networks. Two or more nodes with single antennas cooperate with each other to form a cooperative multiple-input-multiple-output network. In, this paper we examine the use of differential cooperative USTM that avoids channel estimation and also prolong the lifetime of wireless sensor network. Aiming at minimizing the energy consumption per bit we form a differential cooperative energy minimization algorithm by optimally selecting the number of cooperative nodes and finding the route that consumes minimum energy.
