Abstract: The present invention relates to a machine-to-machine communication system using a social network service (SNS), a machine-to-machine communication method, and a machine-to-machine communication server, wherein when the machine-to-machine communication server receives a control information from a second machine-to-machine communication device which has received the control information of a first machine-to-machine communication device through an SNS interface, the machine-to-machine communication server converts the control information into a command recognizable by the first machine-to-machine communication device and transmits the command to the first machine-to-machine communication server such that the second machine-to-machine communication device can receive information corresponding to the command, thereby enabling a user, which is a person, to communicate with a machine-to-machine communication device using an interface of an SNS familiar to the user and to easily control the machine-to-machine communication device or acquire information.

Abstract: A channel estimation apparatus includes a pilot symbol extractor, a least square channel estimator, a Kalman filter and a Wiener filter. The pilot symbol extractor extracts a plurality of pilot symbols from symbols of multiple frequency domains. The least square channel estimator compares the extracted multiple pilot symbols with a plurality of reference pilot symbols and generates a plurality of least square channel frequency responses. The Kalman filter performs Kalman filtering on the least square channel frequency responses. The Wiener filter performs the Wiener filtering on the Kalman filtered least square channel frequency responses.
