1. 2. Consider an OFDM transmitter which transmits an OFDM signal every 0.4 us. If the OFDM systems has 4 subcarriers which employ BPSK, QPSK, 16QAM and 64QAM, respectively. Moreover, the data bits are encoded with an error correcting code with code rate 1/3. Find the transmission rate of the OFDM system.. The duration of the OFDM signal is 1 us. The OFDM systems has 4 subcarriers and the center frequency is 1G HZ. Find the carrier frequency of the 4 subcarriers.
