Patent number: 7539265Abstract: A multiple-input multiple-output code division multiple access (MIMO-CDMA) wireless communication equipment has a transmitter and a receiver. The transmitter has an encoder for receiving and encoding a plurality of data, and sending the data to a quadrature phase-shift keying (QPSK) unit. The QPSK unit conducts QPSK modulating to an output of the encoder and sends it to a space-time block coding (STBC) unit or a space multiplexer to process space-time coding or space coding. A plurality of data frame generating modules generate a data frame respectively based on the output of the STBC unit, a plurality of preamble codes generated by a preamble code spreading unit, a pilot code and a cyclic prefix. The data frame is sent to the receiver via a plurality of transmitting antennas.Type: GrantFiled: November 9, 2005Date of Patent: May 26, 2009Assignee: Chung Shan Institute of Science and Technology, Armaments Bureau, M.N.D.Inventors: Juinn-Horng Deng, Jeng-Kuang Hwang, Po-Tien Lee, Fu-Chin Shau

Publication number: 20090076789Abstract: A pre-verifying method for software/hardware design of a communication system includes simulating a process of sending a data frame from a transmitter to a receiver with a transceiver algorithm meeting a preset specification for obtaining simulation parameters. A transmitter hardware platform sends the data frame via an antenna. A receiver hardware platform receives an echo signal of the data frame and compares each parameter of the echo signal with the simulation parameters. The comparison result of various parameters of the echo signal and the simulation parameters is verified to be in a desired range or not. When the comparison result is not in the desired range, the transceiver algorithm is adjusted. When the comparison result is in the desired range, the transceiver algorithm is converted to a hardware program language format to be written in a programmable module to perform the action of the transmitter and the receiver.Type: ApplicationFiled: November 20, 2008Publication date: March 19, 2009Applicant: Chung Shan Institute of Science and Technology, Armaments Bureau, M.N.D.Inventors: Juinn-Horng Deng, Jeng-Kuang Hwang, Po-Tien Lee, Fu-Chin Shau

Patent number: 7489872Abstract: The present invention is an optical fiber system and method for carrying both CATV and Ethernet signals. The digital signals are translated into higher band by a direct up/down conversion so that analog signals and digital signals are treated as different frequency bands of electrical signals. Then, all the signals are mixed/divided by a power combiner/divider. And then, by using optoelectronic devices, the signals are processed with optoelectronic conversion. The converted optical signals are transmitted in a fiber or a related optical channel having low channel loss yet high capacity. To sum up, the present invention can transmit digital signals together with analog signals in a single wavelength to save the cost of an optical signal system and to provide a convenience on rearranging the system.Type: GrantFiled: September 24, 2004Date of Patent: February 10, 2009Assignee: National Central UniversityInventors: Yi-Jen Chan, Fan-Hsiu Huang, Hsin-Pin Wang, Dong-Ming Lin, Mu-Tao Chu, Shin-Ge Lee, Shun-Tien Lee
