在发射端产生OFDM信号，生成信号的波形已被画出。-OFDM signal generated at the transmitter side, the signal generated waveform is drawn.

Here, wavelets are used in Orthogonal frequency division multiplexing. Wavelets are small waves having amplitude increase starting zero and reduces back to zero. In conventional OFDM, IFFT is used at the transmitter side and FFT is used at receiver.
