Abstract
Orthogonal frequency-division multiplex (OFDM) systems transmit data in blo cks. The two simplest ways of identifying the channel in OFDM systems are t o insert a training sequence between consecutive blocks or to insert pilot tones inside each block. This letter proves that both methods can achieve t he same level of performance under certain conditions on the block length.
