Abstract:

The cyclostationarity property of the OFDM signal embedded pilots is examined based on the theory of cyclostationarity. The final conclusion of this paper can be used as the basis of the cyclostationarity-based blind algorithms. Mathematical deduction and simulation results both show that if the received signal embedded pilots are sampled at the data rate, a cyclostationary sequence can be obtained. And the cyclic period of the sequence equals the length of the OFDM symbol.

Key words: pilot, orthogonal frequency division multiplexing, cyclostationarity, wireless communication channel
