Title: Apparatus and method of chanel estimation for ofdm receiver
Inventor: CHOI JIN KYU
IPC: H04L27/26
Filed: 2007-04-18
Abstract: A channel estimation method of an OFDM system and a channel estimator are provided to correct an instantaneous spread pilot signal power by using a Kalman filter before interpolating a frequency response without a spread pilot. A data rearranging unit(100) rearranges input OFDM(Orthogonal Frequency Division Multiplexing) data according to a channel estimation sequence. A channel estimator(200) acquires a frequency-side channel response by using a spread pilot of the OFDM data and compensates for the channel response by using a Kalman filter. The channel estimator includes a pilot group extractor(201), a Kalman filter gain calculator(207), a Kalman filter compensator(208), a pilot gain calculator(209), and an amplifier(210). The Kalman filter compensator compensates for a current channel estimation value by using a Kalman filter gain and estimates a covariance and a channel estimation value for a next channel.
