... growth does not result in a significant gain in the beginning. Put into more mathematical terms: the function f (x) = x 2 remains close to the abscissa for some time before gaining large values. For ... aims at providing 2D co- ordinates only. But note that the convex combination used here works in the same way in 3D, in particular as we use dimensionless expressions only. Determinin...

... constraint (10) is binding at the optimum. Proof. The accommodation capacity y is an increasing function of p s and p r . However, in decode -and- forward cooperation, the capacity is not a strictly increasing ... multiple access (OFDMA) is one of the most promising solutions to provide a high-performance physical layer in emerging cellular networks. OFDMA is based on OFDM and inher...

... relay knows what destinations are waiting for the lost packets to be retransmitted and then decides how to combine and forward the data to the intended destinations. In the following, we introduce some ... packet in the combined packet should be correctly received by only one destination, similar to the combination performed for packets in Ω 2 and Ω 3 explained in Algorithm 1....
