Suppose an OFDM system decided to use only subcarriers 1 and 2 to modulate data and leave all other subcarriers unused, i.e., not modulating any data, where subcarriers 1 and 2 complete 1 and 2 cycles in a symbol time, respectively. Suppose the transmitter uses BPSK and modulates 1 and -1 on subcarriers 1 and 2, respectively.

Please draw the time-domain OFDM symbol waveform (real part), excluding the cyclic prefix.
