- 초록
- In this paper, Kalman filter method has been used for the estimate of time variant channels in OFDM systems. The estimation is based on Comb- type pilot in frequency domain. The channel coefficients that belong to the pilot subcarriers are estimated by Kalman filter. To reduce complexity, quasi-Newton methods are adapted for updating the gain of Kalman filter. Then, we can estimate channel parameter except for the inverse matrix which needs high complexity by using quasi-Newton methods. ©2010 IEEE.
