在GUI界面上，实现语音读取，描绘时域波形和频域波形，并进行采样和冲采样，最后进行非均匀量化（13折线）！-GUI interface, voice read, depicting the time-domain waveform and frequency domain waveforms, and sampling and washed samples, the final non-uniform quantization broken line (13)

i am uploade matlab code for perfomance analysis of OFDM systyem using different modulation scheme.it simulatoion result is so interesting to propose the modulation scheme when OFDM system is use in application .
