OFDM modulation v72

55 minutes ago    By:proxy      View:54      Download:2

In a basic communication system, the data are modulated onto a single carrier frequency. Theavailable bandwith is then totally occupied by each symbol. This kind of system can lead tointer-symbol-interference (ISI) in case of frequency selective channel.The basic idea of OFDM isto divide the availab...

One way to communicate a message signal whose frequency spectrum does not fall within that fixed frequency range, or one that is otherwise unsuitable for the channel, is to change a transmittable signal according to the information in the message signal. This alteration is called modulation, and...
