Today I will talk about variation of FDM: Orthogonal Frequency Division Multiplexing, or OFDM. OFDM is being used for many of the latest wireless and telecommunications standards, such as Wi-Fi 802.11ac, both 4G LTE and 5G cellular technologies, WiMAX, and many more. It is a very popular multiplexing technology.
So what is big deal of the OFDM? Why does it have many advantages over FDM?

Is this magic? You just explained the same concept my professor explained, but he took an hour and you took only 4 mins. I am thoroughly impressed.

I'm actually kind of emotional/angry over the time wasted through my 'plain english' course material to explain this concept 10% as well as Sunny, a man with a self proclaimed 'Chinglish Accent' I don't know, maybe they need to start writing textbooks with 'Chinglish Accents'

Yeah, Sunny explains everything in an easy way to follow. I'm hooked on his videos for school.

Many professor knows a lot about what they teach, but the problem is that they do not know how to teach well.
