... considered. In this paper, however, we propose a new method for admission capacity planning in OFMDA cellular networks with cooperative relays with power adjustment between source and relay nodes, ... types of links formed in cooperative relaying as shown in Figure 1. In cooperative relaying through decode- and-forward, the achievable rate of the link between the sourc...

... PLLs 5 can be obtained by introducing a loop filter ε(z), with one or two poles respectively, instead of the constant ε in the synchronization s ystem of Figure 7.For instance, in the case of a ... v de- creases with increasing D/d and decreasing ε. Along with v, Figure 4 shows the measure of irreducibility (or strong con- nectivit y) σ (15) as dashed lines. It is interesting to note...
