Abstract
In this paper, a method to optimize packet length for two way relaying systems is suggested. Two source nodes N-1 and N-2 are transmitting data simultaneously to each other through a selected relay. The relay amplifies the sum of N-1 and N-2 signals. N-1 (respectively N-2) retrieves its own signal to be able to detect that of node N-2 (respectively N-1). In the existing literature, a Fixed Packet Length (FPL) is used and it is demonstrated, in this paper, that the proposed Optimal Packet Length (OPL) allows to enhance the system throughput.
