What are the two basic concepts involved with OFDM?
What will be an ideal response?
The first is breaking down the transmission into separate parts and sending each part in parallel simultaneously. That is, instead of sending one long stream of data as with FHSS or DSSS, OFDM sends the transmission in parallel across several channels. The second concept is that these parallel transmissions are sent at a slower rate. Although it may seem counter-intuitive, OFDM actually increases the overall speed by sending the data more slowly.
