    Abstract: A data decoder includes a communication unit receiving a bit signal with encoded data; a first operation unit that bit shifts the bit signal by a first length, corresponding to a length of a spreading code used to encode the data, to generate a first operation stream; a second operation unit generating a second operation stream without the spreading code; a third operation unit that bit shifts the second operation stream by a second length to generate a third operation stream; a fourth operation unit generating a fourth operation stream from which the data is removed using the second operation stream and the third operation stream; and a polynomial generator that decodes the encoded data using the fourth operation stream.

    Abstract: This application relates to a signal filtering device. The device includes a memory and a processor. The processor may generate one or more matrices based on a size of a digital filter bank that generates an output signal by dividing an input signal into a plurality of channels and store in the memory each of the generated one or more matrices to which a plurality of digital filter bank coefficients or a plurality of input signals are assigned. The processor may also partially calculate the stored plurality of digital filter bank coefficients and the plurality of signals based on a number of at least some of the plurality of channels, and calculate the calculated digital filter bank coefficients and signals. The processor may further perform a discrete Fourier transform (DFT) on the calculated signal and compensate for a phase of the discrete Fourier transformed signal according to a preset reference.

    Abstract: This application relates to a method and apparatus for outputting signals. In one aspect, the apparatus includes a signal control unit configured to generate two or more control signals upon two or more conditions, which respectively correspond to the two or more control signals being satisfied. The apparatus also includes a signal output unit configured to output a final output signal depending on the two or more control signals upon an input signal being inputted into the signal output unit.
