Threshold Decision Adaptive Modulation and Coding schemes for OFDM communications

This paper presents a Threshold-Decision Adaptive Modulation and Coding (TD-AMC) technique for OFDM systems. The proposed technique makes the transmitter changes the order of the modulation on each sub-carrier separately depending on the BER on this sub-carrier at the receiver side. The simulation r...

Popis
Shrnutí:This paper presents a Threshold-Decision Adaptive Modulation and Coding (TD-AMC) technique for OFDM systems. The proposed technique makes the transmitter changes the order of the modulation on each sub-carrier separately depending on the BER on this sub-carrier at the receiver side. The simulation results show an overall average gain in the BER performance of the proposed technique of normal fixed order modulation techniques.
