Abstract: A Discrete Fourier Transform (DFT) apparatus is provided. The DFT apparatus includes a first delay, a second delay, an operator, and a multiplier. The first delay delays one sampling data by N-sample in a time axis when the one sampling data is input. The second delay delays an output value of a frequency component for a previous sampling data by 1-sample. The operator performs an operation based on the input one sampling data, the one sampling data delayed by the N-sample in the time axis, and the 1-sample delayed output value of the frequency component for the previous sampling data. The multiplier multiplies an output value from the operator by a twiddle factor  j  2   π   kn N . Therefore, a complexity of a stream DFT operation can be reduced.

Abstract: An apparatus and a method for processing reduced bandwidth Envelope Tracking (ET) and Digital Pre-Distortion (DPD) are provided. The apparatus includes a Crest Factor Reduction (CFR) unit, a resealing Digital Pre-Distortion (DPD) unit, an envelope converter, a Supply Modulator (SM), and a Power Amplifier (PA). The CFR unit suppresses an increase of a side lobe occurring when a Peak to Average Power Ratio (PAPR) decreases with respect to a signal generated in a baseband according to a standard and passes through a transmit (Tx) filter. The resealing DPD unit receives an original envelope amplitude and a reduced bandwidth envelope amplitude of an In-phase/Quadrature-phase (I/Q) signal output from the CFR unit to perform a pre-distortion process. The envelope converter converts an envelope signal to a reduced bandwidth envelope signal based on the I/Q signal output from the CFR unit.
