Abstract: |
In this paper we develop a power allocation scheme for a single-relay
system applying Decode-Forward (DF) based on the resulting bit error
rate (BER) at the destination. First, an analytical expression for the
BER for M-QAM modulation considering estimation errors at the relay is
derived. Based on this expression, the total transmit power is
optimally assigned to the source and the relay in order to minimize the
probability of errors at the destination. The preciseness of the derived
closed form expression as well as the superior performance of the
proposed DF-based relaying system are demonstrated by simulation
results.
