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.

OFDM 实现数据图像和信息的传输，内含发射端和接收端，以及卷积码-OFDM realize image data and the transmission of information, containing transmitter and the receiver, and the convolution code

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.
