Abstract :
This paper studies a broadband relay network model with multiple source nodes, multiple relay nodes and a single destination node. The capacities using different multiple access schemes (joint coding/decoding and OFDMA) under two relay schemes are derived, respectively. Numerical results are evaluated to compare the two multiple access schemes.
