摘要： A digital television receiving system includes a frame encoder, a data randomizing and expanding unit, a group formatter, a block processor, a deinterleaver, and a multiplexer. The frame encoder encodes an enhanced data frame for error correction. The data randomizing and expanding unit randomizes the encoded enhanced data and expands the randomized enhanced data. The group formatter forms a group of enhanced data having head, body, and tail regions and inserts the expanded data and transmission parameters into the body region. The block processor codes the group of enhanced data, and the deinterleaver deinterleaves the coded enhanced data. The packet formatter formats the deinterleaved enhanced data into enhanced data packets.

摘要： A digital television (DTV) receiving system includes a known data detector, and a channel impulse response (CIR) estimator, a CIR calculator, a coefficient calculator, and a multiplier. The known data detector detects positions of known data and field sync data included in a data group. The CIR estimator estimates CIRs of the data included in the data group using the detected positions of the field sync data and the known data. The CIR calculator performs interpolation or extrapolation based on a characteristic of each data region included in the data group. The coefficient calculator calculates equalization coefficients using the estimated CIRs, and the multiplier multiplies the data in the data group with the coefficients.
