What is OFDM Basics and Cyclic Prefix Analysis about?

1) OFDM works by dividing a high-rate data stream into multiple lower-rate streams that are transmitted in parallel over subcarriers. A cyclic prefix is added to each transmitted symbol to mitigate inter-symbol interference. 2) At the receiver, the cyclic prefix is removed and an inverse fast Fourier transform reconstructs the original data by combining the signals from each subcarrier. Channel equalization is then performed by dividing each subcarrier by the estimated channel response. 3) Timing and fr
