Patent number: 7154961Abstract: An ARQ (re-) transmission method of transmitting data in a wireless communication system wherein data packets are transmitted from a transmitter to a receiver, using a first transmission and a second transmission based on a repeat request. The method comprises the steps of modulating data at the transmitter using a first signal constellation pattern to obtain a first data symbol. The first data symbol is transmitted as the first transmission to the receiver using a first diversity branch. Further, the data is modulated at the transmitter using a second signal constellation pattern to obtain a second data symbol. Then, the second data symbol is transmitted as the second transmission to the receive over a second diversity branch. Finally, the received first and second data symbol data symbol are diversity combined at the receiver. The invention further relates to a transmitter and a receiver embodied to carry out the method of the invention.Type: GrantFiled: October 18, 2002Date of Patent: December 26, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Christian Wengerter, Alexander Golitschek Edler Von Elbwart, Eiko Seidel

Patent number: 7152198Abstract: A coding/decoding technique capable of increasing the error correcting decoding performance and improving the communication quality. This technique divides, through code block segmentation prior to error correcting coding, transmission data with CRC-bit added into a predetermined number of code blocks so that the data length of each code block is an integer multiple of the data length of each transport block and ensures that CRC-bit exists at the end of each code block. Then, the technique performs error correcting coding on each code block after the division.Type: GrantFiled: April 20, 2001Date of Patent: December 19, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Kuniyuki Kajita
