Disclosed herein are an apparatus and method for providing FTN communication using transmit diversity. A transmission apparatus generates a signal to be output through diversity modulation. A diversity order of diversity modulation may be set based on an FTN parameter, such as a variable for adjusting sampling time or a symbol transmission speed. When the diversity order is set based on the FTN parameter, the FTN parameter and the diversity order may be set so as to satisfy a QoS required of the transmission apparatus, such as a transmission rate and a Bit Error Rate. Depending on the circumstances, the set FTN parameter and diversity order may be provided to a reception apparatus that is to receive the output signal.

Disclosed herein are a method and apparatus for iterative interference cancellation and channel estimation in a system based on FTN communication including a pilot. Interference of a pilot symbol on a data symbol is estimated, and the estimated interference is eliminated from a sequence of data symbols. When demodulation and channel decoding are performed on the sequence of data symbols, interference between data symbols and interference of a data symbol on a pilot symbol are estimated. Such estimation is repeatedly performed, and as FTN interference is repeatedly estimated and eliminated, channel estimation performance is improved, and through the improved channel estimation performance, the reception performance of the entire system is improved.

The present invention relates to powder detergent granules that are substantially free of a water-insoluble component such as zeolite or silica, a method for manufacturing the powder detergent granules and a copolymer having various properties useful as a detergent component. The powder detergent granules of the present invention are substantially free of a water-insoluble component, and thus exhibit good solubility and washing performance (stain removal performance) in cold water, do not leave residue after laundry, and reduce the likelihood of a caking phenomenon during manufacture and storage. And, the powder detergent granules of the present invention are substantially free of zeolite or silica that absorbs a liquid component, but are capable of accommodating a considerable amount of liquid surfactant. Further, a copolymer comprising acrylic acid monomer unit and 2-acrylamido-2-methylpropane sulfonic acid monomer unit, an acidic water-soluble polymer of the present invention, is useful as a detergent component in various aspects.
