| Abstract: | Orthogonal Frequency Division Multiplexing (OFDM) has high f requency utilization and is robust to interference. It has attracted more and mo re attention. Channel estimation is needed in order to eliminate the influence o f channels in OFDM systems. In this paper, several channel estimation methods fo r OFDM are introduced. MMSE, LS, PSAM and blind methods and their characteristic s are analyzed and compared. |
