Abstract: Disclosed is a 5G or pre-5G communication system to be provided so as to support a data transmission rate higher than that of a 4G communication system such as long term evolution (LTE). According to the present disclosure, a method for transmitting a signal in a communication system supporting multi-user access comprises the steps of: transmitting, to a receiving device, information indicating a codebook formed on the basis of at least two signal constellations for sparse code multiple access (SCMA) transmissions; and transmitting signals on the basis of the codebook, wherein the at least two signal constellations are generated on the basis of energy values of symbols of a pre-given mother signal constellation and sizes of the symbols of the mother signal constellation.

Abstract: An electronic circuit includes a reference ADC, a delay circuit, and a main ADC. The reference ADC converts an input signal to an upper bit string of output data, in response to a reference clock. The delay circuit delays a source clock by a delay time to output a main clock. The main ADC converts the input signal to a lower bit string of the output data, in response to the main clock. When a value of the most significant bit included in the lower bit string is identical to a value of the bit which is adjacent to the most significant bit and lower than the most significant bit, the delay time is adjusted based on a direction in which a level of the input signal is changed and the value of the most significant bit of the lower bit string.

Abstract: A method for controlling a vehicle relates to a voice masking technology for allowing only a specific passenger among passengers in the vehicle to listen to a voice communication signal such as a dial tone, and the technology inhibits the remaining passengers other than the specific passenger from listening to the voice communication signal. The vehicle includes a voice signal receiver to receive a voice signal, a speaker provided in the vehicle to output the voice signal, and a controller to perform frequency conversion of the received voice signal. In particular, the controller generates a masking sound for inhibiting transmission of information contained in the voice signal on the basis of a frequency band of the converted voice signal, and generates a control signal in a manner that the generated masking sound is output to a predetermined region of an indoor space of the vehicle.
