Abstract: In order to ensure the validity and reliability of communication, it’s necessary to know the channel state information(CSI) of orthogonal frequency division multiplexing (OFDM) system. This paper proposes a method to dectect the state information for channels, based on the pilotsymbolaided estimation in OFDM systems. The experiment results show that the method can efficent evaluate the state of channels by finding out appropriate parameters of CSI.

Key words: CSI, pilot symbols, OFDM, channel estimation
