可实现稳定高速无线数据传输的正交频分复用技术

OFDM Technology With Steadier and Higher Capability in Wireless Data Transmission

正交频分复用是一种多载波调制技术,具有良好的抗多径衰落的能力和非常高的信道利用率。它的信号解调和调制的过程可通过快速付立叶变换及其反变换来实现。

OFDM is a MCM technology which was often used in the channels. It has better capadility against the multipath fading and higher spectrum efficiency. The process of signals production and demodulation is a transform process of IFFT/FFT.
