This study performed an experimental test to derive the characteristics of compressive strength, het of hydration and creep of roller compacted concrete. The main variable of strength test are cement content and fly ash content. The heat of hydration test was performed using MARUTO CH-50-CA and dreep test was carried out according to KS F 2453.

In this paper, a PN code tracking loop with extended Kalman filter (EKF) is proposed for a direct-sequence spread-spectrum. EKF is used to estimate amplitude and delay in a multipath fading channel. It is shown that tracking error performance is significantly improved by EKF compared with a conventional tracking loop.
