摘要：

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