OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术，实际上OFDM是MCM(Multi Carrier Modulation)，多载波调制的一种。通过频分复用实现高速串行数据的并行传输, 它具有较好的抗多径衰落的能力，能够支持多用户接入。 [1] OFDM技术由MCM（Multi-Carrier Modulation，阅读笔记-Modulation and Coding Design for Simultaneous Wireless Information and Power Transfer

PCM(Pulse-code modulation)脉冲编码调制 在音频处理中，我们会经常听到PCM数据，那么什么是PCM数据呢？ PCM数据就是模拟信号经过PCM以后的数字信号，PCM就是把音频信号由模拟信号（时间连续，取值连续）转为数字信号（时间离散，取值离散）的过程。数字信号有很多优点，因此一般传输的信号都是数Pulse-width Modulation (PWM)
Pulse-width Modulation (PWM) Pulse-width modulation (PWM) is a technique that modifies the duty-cycle of a pulsing signal to encode information or to control the amount of energy provided to a charge.
