How modified data for PAPR reduction in OFDM helps us in recovering the original data at the receiver end?

In the PTS method of PAPR reduction, we are modifiying the OFDM data to reduce the PAPR. That is ok. Once we are getting the modified data with reduced PAPR, this modified data is sent at the...

How does data transmission happen in OFDM?

"If carrier is single, we are able send only one vector of symbols on the channel by using the carrier. In the case of OFDM systems, we are going to pass multiple carriers through a single channel...
