Hi,

Pilots are crucial for synchronization and channel estimation in OFDM systems. They transmit known signals at specific frequencies, which helps the receiver quickly identify and synchronize with the incoming signal.

They are inserted at defined intervals within the OFDM frame to enable the receiver to estimate the channel's frequency response. This estimation allows the receiver to compensate for any distortions or variations introduced by the channel.
