We evaluate the outage probability of cognitive amplify-and-forward relay networks with cooperation between certain secondary users chosen by multi-relay selection based on the underlay approach, while adhering to the interference constraint on the primary user. A max-min strategy is employed to perform best relay or multi-relay, i.e. between two and four relays, selection. We obtain analytical expressions...
The TTF-III power coupler adopted for the ILC baseline cavity design has shown a tendency to have long initial high power processing time. A possible cause for the long processing time is believed to be multipacting in various regions of the coupler. To understand performance limitations during high power processing, SLAC has built a flexible high-power coupler test stand. The plan is to test individual...
