Patent application numberDescriptionPublished
20100041413RADIO BASE STATION DEVICE, RADIO TERMINAL DEVICE, AND RADIO COMMUNICATION SYSTEM - It is possible to provide a radio communication system, a radio base station device, and a radio terminal device capable of reducing the power consumption in a radio terminal device without thinning pilot signals used for measuring upstream line quality. In the radio base station device (02-18-2010
20100070828TRANSMISSION METHOD, TRANSMITTER APPARATUS AND RECEPTION METHOD - A transmitter apparatus wherein a simple structure is used to successfully suppress the degradation of error rate performance that otherwise would be caused by fading or the like. There are included encoding parts (03-18-2010
20100077276TRANSMITTING DEVICE, RECEIVING DEVICE, ENCODER, AND ENCODING METHOD - In such a relationship between information transmitted by a primary BCH, for example, and information transmitted by a non-primary BCH as a case of the transmission for a first information sequence that is easy to keep receiving quality and a second information sequence that is difficult to keep receiving quality, a transmitting device and a receiving device are disclosed for making it possible to improve an error rate of the second information sequence. In the devices, an encoder (03-25-2010
20100118987Transmitter Apparatus, Receiver Apparatus, and Wireless Communication Method - When space-time block code signals are to be transmitted, the patterns thereof are changed in accordance with data to be transmitted. This advantageously allows a good-quality data transmission to be achieved by the space-time block code signals. In addition, since data can be transmitted by use of the patterns of the space-time block code signals, the data transmission efficiency can be improved.05-13-2010
20100172421MIMO RECEIVER AND MIMO COMMUNICATION SYSTEM - An MIMO receiver and MIMO communication system which can have a small hardware scale even if the number of antennas used for MIMO communication. In a radio communication device (07-08-2010
20100192047TRANSMITTING DEVICE AND TRANSMITTING METHOD - A transmitting device and method enabling improvement of the reception quality on the receiving side when the LDPC-CC (Low-Density Parity-Check Convolutional Codes) encoding is used. The transmitting device (07-29-2010
20100218066ENCODING DEVICE AND DECODING DEVICE - Disclosed are an encoding device and a decoding device which can effectively reduce the decoding failure frequency in LDPC encoding/decoding. A loss correction encoding device (08-26-2010
20110113300DECODING METHOD, DECODING DEVICE, INTERLEAVING METHOD, AND TRANSMITTER - A decoding device allowing a high-speed decoding operation. In a decoding section (05-12-2011
20110138258ENCODING DEVICE AND DECODING DEVICE - An encoding device and decoding device for improving an error floor while taking advantage of the features of a convolutional code capable of encoding/decoding an information sequence with an arbitrary length are disclosed. An error correction encoding section (06-09-2011
