基于DSP2812的永磁同步电机矢量控制源程序(DSP2812-based vector control of PMSM source)

OFDM仿真程序，信道估计采用LS,MMSE,LMMSE,DCT等方法，做了个比较，ofdm那个是主程序(OFDM simulation program, channel estimation using LS, MMSE, LMMSE, DCT and so on, made a comparison, ofdm that is the main program)

QPSK的编译 设定噪声为高斯白噪声，对2ASK、2FSK、2PSK、2DPSK等各种调制方式及相应的主要解调方式下（分相干与非相干）的误码率进行统计，并与理论值进行比较，以图形方式表示误码率与信噪比间的关系。(QPSK compiled Set the noise is Gaussian white noise, right 2ASK, 2FSK, 2PSK, 2DPSK variety of modulation and demodulation mode corresponding to the main (sub-coherent and non-coherent) error rate statistics, and with the theoretical value comparison, a graphical representation of bit error rate and SNR relationships.)
