Description: OFDM的英文全称为Orthogonal Frequency Division Multiplexing，中文含义为正交频分复用技术。这种技术是HPA联盟（HomePlug Powerline Alliance）工业规范的基础，它采用一种不连续的多音调技术，将被称为载波的不同频率中的大量信号合并成单一的信号，从而完成信号传送。由于这种技术具有在杂波干扰下传送信号的能力，因此常常会被利用在容易外界干扰或者抵抗外界干扰能力较差的传输介质中。-OFDM The English called Orthogonal Frequency Division Multiplexing, Chinese meaning is orthogonal frequency division multiplexing. This technique is the basis of HPA Alliance (HomePlug Powerline Alliance) industry standard, which uses a discrete multi-tone technique, a different carrier frequency will be referred to the large number of signals into a single signal, thereby completing the signal transmission. Because of this technology has the ability to transmit signals at clutter, so often can be exploited in an easily resist outside interference or poor outside interference in the transmission medium.

Description: OFDM技术由MCM（Multi-Carrier Modulation，多载波调制）发展而来。OFDM技术是多载波传输方案的实现方式之一，它的调制和解调是分别基于IFFT和FFT来实现的，是实现复杂度最低、应用最广的一种多载波传输方案。-Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital data on multiple carrier frequencies. OFDM has developed into a popular scheme for wideband digital communication, used in applications such as digital television and audio broadcasting, DSL Internet access, wireless networks, powerline networks, and 4G mobile communications.
