HLP A+ Modbus 标准通讯协议格式，上位机发送数据格式，正确时变频器返回数据格式(This bit will be set to logic 1 when the receive buffer has been read and contains no new information. If there is new information available in the receive buffer that has not been read, this bit will return to logic 0. RXBMT = 1 when in Master Mode.)

viterbi decoder 2/3 rate

ofdm系统模型，包含信道估计 FFT变换 QPSK 16QAM调制 插入导频等，非常全面。(OFDM system model, including channel estimation FFT transform QPSK 16QAM modulation insert Pilot and so on, very comprehensive.)

通过伪随机序列进行频率调制，并对相位连续性进行优化。调制信号的自相关函数可以通过谱修正进行旁瓣抑制(Frequency modulation is performed by pseudo-random sequence and phase continuity is optimized. The autocorrelation function of modulation signals can be sidelobe suppressed by spectral correction)
