OFDM modulation v72

2015-04-15 10:30    By:proxy      View:88      Download:3

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...
