A modem chip communicates with a radio frequency (RF) chip and includes a digital interface configured to receive data including a plurality of samples from the RF chip based on digital communication. A logic block generates a frame synchronization signal based on a clock signal in the modem chip, provides the generated frame synchronization signal to the digital interface, and receives the plurality of samples in synchronization with the frame synchronization signal.

Modem and RF chips, application processor including the same and operating method thereof

Provided is an apparatus and method for analyzing a biological signal. The apparatus may measure the biological signal, detect a noise signal influencing the electrical characteristics of the measured biological signal, and display the measured biological signal by distinguishing a normal section of the measured biological signal from an abnormal section of the biological signal.

Method and apparatus for measuring a biological signal

A turbo decoder and a decoding method are disclosed, which use a Maximum A Posteriori (MAP) algorithm in order to perform iterative decoding. The method has the steps of sequentially receiving input data in a memory having a predetermined window size and performing a forward metric calculation for the input data so that the input data has a four window size, performing a first backward metric calculation for the input data and outputting first valid data when the data are input to the memory by twice the window size, and performing a second backward metric calculation for the input data and outputting second valid data when the data are input to the memory by three times the window size.

Decoder and method for performing decoding operation using map algorithm in mobile communication system

A method of designing an optimum encryption algorithm and an optimized encryption apparatus are disclosed. In the encryption apparatus, a function block produces a first ciphertext of lengthby encrypting a first plaintext of lengthwith an encryption code of lengthgenerated from a key scheduler, and a second ciphertext of length m by encrypting the first ciphertext with a second plaintext of length m under the control of a controller. A memory stores the second ciphertext.
