    • PURPOSE: A transmission method of digital broadcast signals, a transmission device, a reception method, a reception device, and a transmission frame structure thereof provide a single consistent transmission frame structure supporting various transmission modes, thereby providing various forms of services to a user. CONSTITUTION: A stream providing unit (100) converts service components of each program into streams. A multiplexing unit (200) modulates the streams into a predetermined mode according to a transmission mode. A transmission frame generator (300) generates a transmission frame based on the stream information allocated to each sub-channel and the multiplexing information due to the transmission mode. The transmission frame includes a frame body including the data information in respect to the services provided by the transmission frame and a frame header including the multiplexing information of the transmission frame.

    • PURPOSE: A channel estimation device and a method thereof are provided to reduce influence based on a small channel tap by applying a weight value to an estimated channel coefficient. CONSTITUTION: A first channel response estimation unit(110) estimates a first channel impulse response from a reception signal. A weight calculation unit(120) determines a weight value applied to each channel coefficient by using the first channel impulse response. A second channel response estimation unit(130) estimates second channel impulse response by applying the weight value to the first channel impulse response. The weight calculation unit includes a correlator. The correlator calculates a correlation value by using the first channel impulse response.
