Node Switching Rate in Cooperative Communications
In opportunistic relaying systems, only the relay with best channel condition among K relays is selected to take part in cooperation. This setup efficiently achieves diversity gain. However, the high switching rate of such systems may be undesirable due to practical implementation issues, for example, the corruption of the data signal by receiver switching transients, or channel estimation and synchronization failures due to excessive switching, as well as network control switching overheadsdoi:10.7939/r32040 fatcat:sg37g6cyuraebfwbbvrf6dw3ju
