![]() However, the applications of the OFDM are increasing rapidly in the fields of wired communication and wireless communication. The basic idea of using FFT-OFDM was explained by different authors. Guard bands are used to separate the symbols present in the OFDM, this guard band separation will resist the multipath effects. Designing an OFDM will reduces the multipath effect at receiving end, by dividing the wide-band frequencies into many narrow-band frequencies this dividing process is carried out to avoid the interference that is caused during multipath effect. In OFDM a stream of data is transmitted and they are orthogonal to one another. Orthogonal Frequency Division Multiplexing (OFDM) is a technique for transmitting multicarrier signals. published by seventh sense research group Reshma M " Comparative Study on DWT-OFDM and FFT-OFDM Simulation Using Matlab Simulink ", International Journal of Engineering Trends and Technology (IJETT), V43(5),302-304 January 2017.
