We use simulation results to show the performance of the water filling algorithm. Simplify this question into a OFDM based communication network with one transmitter and one receiver. It is assumed that the total power of Pmax = 1 w and the total ban

The number of subchannel varies from (4, 16, 32, 64), using Matlab to simulate relay communication in different network mode: 1) water filling only 2) buffer only 3) buffer + water-filling -The number of subchannel varies from (4, 16, 32, 64), using

one destination.he channel capacity between the source and the relay is usually different from that between the relay and destination because of the independent fading on the two links. The network capacity for each channel realisation is constrained
