摘要： In a method and device to align phases of a first clock signal and a second clock signal, include a phase detector, a delay generator, and a controller. The phase detector is configured to generate a preceding signal and a succeeding signal with respect to the first clock signal to detect a relationship between phases of the first clock signal and the second clock signal. The delay generator is configured to delay the first clock signal when the second clock signal falls behind the succeeding signal with respect to the first clock signal. The controller is configured to determine whether the phases of the first clock signal and the second clock signal are aligned with each other according to the relationship detected by the phase detector.

摘要： A system and method are provided to efficiently provide coverage within a large scale of a building by identifying user equipment (UE) on a floor by floor basis using a distributed antenna system (DAS) and pseudo timing advance values (TA) assigned to each floor. By applying different pseudo delays on a plurality of distributed antenna basis located at each floor, a base station can know a floor at which a user equipment is located through a timing advance value of the user equipment. When a traffic amount increases based on the measured traffic amount of each floor, the base station may increase a carrier and adjust an amplifier output on a floor by floor basis, thereby efficiently using power and maintaining a user's quality of experience (QoE).

摘要： In a data encoding method for a communication between semiconductor chips, a data sequence is received. The data sequence includes multiple characters and multiple identification codes coupled to the characters, respectively. The data sequence is stored in a buffer in a unit of a predetermined number of pairs of characters and identification codes. Whether at least one control character is stored in the buffer is determined based on the identification codes stored in the buffer. When at least one control character is stored in the buffer, the at least one control character is converted to at least one internal control character, respectively. When multiple control characters are stored in the buffer, at least one internal control character includes a reference number representing a location of a sequentially next control character in the buffer. A first type data block is generated. The first type data block includes data characters stored in the buffer and the at least one internal control character.
