Abstract:
The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-generation (4G) communication system such as long term evolution (LTE). Disclosed are an apparatus and a method for a permutation of a block code in a wireless communication system. A method of operating a transmitting node in a wireless communication system includes: determining a permutation matrix according to a block code scheme; generating symbols corresponding to a plurality of antennas based on the block code scheme and the permutation matrix; and transmitting the symbols to a receiving node through the plurality of antennas. The permutation matrix is determined based on a number of blocks and an arrangement structure of the plurality of antennas, and the number of blocks comprises a number of sub-blocks within a code block corresponding to the permutation matrix.
Abstract:
A delay locked loop includes a delay line, a delay circuit, a phase detector, a delay code generator, and a delay controller. The delay line may delay an input clock signal in units of unit delay in response to a delay control code to generate an output clock signal. The delay circuit may delay the output clock signal to generate a delay clock signal. The phase detector may compare the input clock signal and the delay clock signal to generate a phase detection signal. The delay code generator may compare the input clock signal and the delay clock signal to detect a phase difference therebetween, and generate a delay code using the phase difference. The delay controller may generate the delay control code using the delay code and the phase detection signal.

Abstract:
A three-dimensional (3D) semiconductor device may include a stack of chips, including a master chip and one or more slave chips. I/O connections of slave chips need not be connected to channels on a motherboard, and only electrode pads of a master chip may be connected to the channels. Only the master chip may provide a load to the channels. A through-substrate via (TSV) boundary may be set on a data input path, a data output path, an address/command path, and/or a clock path of a semiconductor device in which the same type of semiconductor chips are stacked.
