Closed-form expression for the BER of m-QAM-OFDM systems over time- and frequency-selective wireless channels


The broadcast DVB-T system is an m-QAM-OFDM communication system that includes pilot-symbolassisted modulation (PSAM) in order to enhance channel estimation at the receiver. This characteristic makes DVB-T suitable for a mobile reception, over timeand frequency-selective wireless channels. In this work, a closed-form expression for the BER as a function of… (More)
