Patent number: 10687285Abstract: A transmitting method, a transmitter, a receiver and an associated scheduling method for control signal and data signal are provided. The transmitting method includes following steps. Firstly, a first control power and a first data power are respectively allocated to a first control signal and a first data signal which are to be transmitted with a first sub-carrier in a first time duration. The first control power and the first data power are different. The first control signal and the first data signal are multiplexed by superimposing the first control power and the first data power before the multiplexed first control signal and the multiplexed first data signal are transmitted.Type: GrantFiled: December 28, 2015Date of Patent: June 16, 2020Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Chien-Min Lee, Tzu-Ming Lin, Keng-Te Liao, Chia-Han Lee

Patent number: 9277454Abstract: A transmitter, a receiver, a transmitting method and a receiving method are proposed. the transmitter, adapted for an user equipment (UE) of a data transmission scheme using a contention-based radio access based on single-carrier frequency division multiplexing access with code division multiplexing (SC-FDMA-CDM) includes a memory unit and a processing unit. The memory unit stores a plurality of parameters. The processing unit is coupled to the memory unit, selects one of the parameters and generates a resource pattern by executing a resource pattern generation process according to the selected parameters, wherein the resource pattern includes a physical index of a plurality of resource blocks and a spreading code index. The communication unit is coupled to the processing unit, generates an uplink transmitting signal according to the resource pattern with a plurality of transmitting data bits.Type: GrantFiled: November 5, 2013Date of Patent: March 1, 2016Assignee: Industrial Technology Research InstituteInventors: Keng-Te Liao, Chia-Han Lee, Tzu-Ming Lin, Chien-Min Lee

Patent number: 9256324Abstract: An interactive operation method of an electronic apparatus is provided. An image sequence is captured by an image capturing unit. An image pre-processing is executed on an image of the image sequence. A fingertip candidate region is obtained from the image. Whether the fingertip candidate region is connected with a hand region is determined. If the fingertip candidate region is connected with the hand region, the fingertip candidate region serves as a target fingertip region. Whether a click event occurs is determined by continuously tracking the target fingertip region. When the click event occurs, a corresponding function is executed.Type: GrantFiled: December 19, 2013Date of Patent: February 9, 2016Assignee: National Taiwan University of Science and TechnologyInventors: Bai-Ruei Huang, Chang-Hong Lin, Chia-Han Lee
