该文件给出了单载波频域均衡中MMSE均衡方法的MATLAB实现，其中包含调制解调，交织，解交织以及编译码，包含了整个通信系统的各部分，希望对大家有帮助。(The document gives the MATLAB single-carrier frequency domain equalization MMSE equalization method, which contains modulation and demodulation, interleaving, de-interleaving and encoding and decoding, including the various parts of the whole communication system, we want to help.)

变频调速是改变电动机定子电源的频率，从而改变其同步转速的调速方法。变频调速系统主要设备是提供变频电源的变频器，变频器可分成交流-直流-交流变频器和交流-交流变频器两大类，目前国内大都使用交-直-交变频器。(Variable frequency speed regulation is the frequency of changing the stator power supply of the motor, thus changing the speed regulation method of the synchronous speed.Variable frequency speed regulation system is the main equipment to provide frequency conversion power of inverter, the inverter can be divided into ac - dc - ac frequency converter and ac - ac frequency converter two kinds big, cross - straight - to pay inverter are mostly used in China at present.)

数字调制就是把数字基带信号的频谱搬移到高频处，形成适合在信道中传输的带通信号。基本的数字调制方式有振幅键控（ASK）、频移键控（FSK）、绝对相移键控（PSK）、相对（差分）相移键控（DPSK）。在接收端可以采用想干解调或非相干解调还原数字基带信号。 (Digital modulation is the spectrum shifting to high frequency digital baseband signals, suitable for the formation of bandpass signal transmission in the channel. Digital modulation basic amplitude keying (ASK), frequency shift keying (FSK), the absolute phase shift keying (PSK), relative (differential) phase shift keying (DPSK). At the receiving end can be used to dry the demodulation or non coherent demodulating the digital baseband signal. )
