What limitations or challenges are associated with OFDM, and how can they be mitigated in real-world implementations?

How does OFDM enable efficient utilization of the available spectrum through its ability to divide the total bandwidth into multiple orthogonal subcarriers, and how does this contribute to its resistance against frequency-selective fading in wireless channels?

What are the advantages of using OFDM in comparison to traditional transmission techniques, such as single-carrier modulation and frequency division multiplexing (FDM), in wireless communication systems?

What is the intuition behind using guard bands? How does this affect the signal? How is it different in OFDM and FDM?

What are the advantages of using the sinc function as the basis for subcarriers in OFDM, and how do these advantages contribute to efficient and robust ...Read more

What would be the impact, of using OFDM, on bit error rates due to AWGN (surrounding additive white gaussian noise)? Are OFDM signals more prone to error, less prone, or remain unaffected by the use of OFDM compared to FDM ...Read more

What are the factors that directly and indirectly influence and decide the data rates of OFDM communication?

Without Cyclic Prefix in OFDM, how would delay spread affect the quality of signal communication?

In the frequency domain, we describe each carrier to be a sinc function peaking at its own carrier frequency. Why do we represent it with a sinc function and not a wide peak that is zero for all frequencies outside ...Read more
