OFDM系统中16QAM调制下在载波不同时得到的误码率曲线图-Modulation 16QAM OFDM system carrier is not at the same time to get under the BER curves

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.
