OFDM modulation v72

2015-09-04 11:57    By:proxy      View:92      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...

Orthogonal Frequency Division modulation

2015-08-20 00:25    By:Nindya      View:38      Download:0

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, whether wireless or over copper wires, used in applications such as digital television and audio broadc...
