Abstract: A receiving apparatus includes: a first decoder configured to decode a signal transmitted through a first layer from a layered division multiplexing (LDM) signal using a parity check matrix to generate low density parity check (LDPC) information word bits and parity bits; an encoder configured to encode the LDPC information word bits, generated by decoding the signal transmitted through the first layer, using the parity check matrix to generate parity bits corresponding only to preset columns in the parity check matrix; and a second decoder configured to decode a signal obtained by removing, from the LDM signal, a signal corresponding to the LDPC information word bits generated by decoding the signal transmitted through the first layer, the parity bits generated by the encoder, and the parity bits generated by the first decoder except the parity bits generated by the encoder, thereby to generate information word bits transmitted through a second layer.

Abstract: Disclosed are systems, methods and devices for improving audio processing and playing multiple sounds using fewer resources. Various implementations may create audio files, in some cases from a single sample of a type of sound, where the files represent specific quantities of that type of sound, such as 10 footsteps or 1000 claps. Given a desired target number of sounds to play, various implementations determine an appropriate combination of the employable audio files to represent the desired number of sounds, and play or render the combination as an approximation of the desired target number of sounds. By using single audio files that represent and sound like multiple instances of a specified type of sound, the various implementations use significantly fewer computing and audio resources than playing an equivalent number of audio files each of which contains a single instance of the specified type of sound.

Abstract: A method for receiving data in an unlicensed band and a device using the same are provided. The device receives discovery reference signal (DRS) configuration for a DRS period from a primary cell operating in a licensed band, and checks the reception of the DRS in a DRS subframe of a secondary cell operating in the unlicensed band according to the DRS period. When the DRS is received in the DRS subframe, the device determines the reception quality of a downlink data burst on the basis of the received DRS.

Abstract: The present disclosure provides a multi-carrier time-division multiplexing (MC-TDMA) modulation and demodulation method and system. Before multi-carrier modulation is performed on an input symbol, an interleaving allocation and an FFT may be performed, a time domain symbol may be transformed into a frequency domain symbol signal to perform a MDFT treatment. A sending end may adopt an analyzing filter bank structure, and pre-filtering and an IFFT may be performed on a signal successively. A pre-filter may be positioned between an NM point FFT and an M point IFFT, a PAPR value of the system may be reduced using the symmetry of a coefficient of a filter, and a frequency domain symbol signal may be allocated to different sub-bands for multi-carrier modulation.
