- A symbol is modulated on to orthogonal sub-carrier.
- Modulation is done by using IFFT.
- High spectral efficiency.
- Demodulation is done by using FFT. ( Demodulation of received signal )
- Low efficiency to time synchronization techniques.
- Better resultant quality of fading.
- Very sensitive to time-frequency synchronization.
- Simplified channel equalization.
- Immunity to intersymbol interference.
- No inter-carrier guard band.
- Orthogonal carrier and control overlapping band.
- Improved quality of narrowband interference.
- Robust against intersymbol interference.
- Fading caused by multi-path propagation.
- Decoding and de-interleaving.
- Orthogonality is maintained during channel transmission.

Hello, My name is Jay Solanki and I am a mechanical engineer and MBA postgraduate in Telecom and Marketing field. I have been in the Digital marketing field for a few years now, learning more about the field and myself every day. I started a website on mechanical engineering mechanicalfunda.com in 2015. Since then it has given me a passion for learning as well as allowed me to step into another niche called difference or comparison of two similar kinds of terms differenceguides.com. Also, I have interest in Electronics field as my Postgraduation in Telecom and Marketing field, I started ecstuff4u.com too. I spend most of my time singing, playing sports, and writing content. I love to share expertise and knowledge in the above mentioned field.
