20090201797 | RADIO COMMUNICATION SYSTEM, RECEIVER, RECEIVING METHOD, TRANSMITTER, TRANSMITTING METHOD, AND DEVICE FOR AND METHOD OF CALCULATING DELAY TIMES FOR MULTI-CARRIER TRANSMISSION - Multi-carrier transmission is performed without inserting a repetitive signal into guard interval periods. A transmitter provides guard interval periods by using a null signal to save transmission power and prevent the deterioration of the SN ratio. Delayed waves at the head of each received symbol cause high-frequency waves to occur and carriers to interfere with one another. Accordingly, a receiver adds a component following each received symbol to a delayed-wave component at the head of the received symbol. As a result, the delayed-wave component at the head of the received symbol and the added component become continuous in wave form and subcarriers do not interfere with each other. | 08-13-2009 |
20090207888 | Transmission Apparatus, Transmission Method, Reception Apparatus, Reception Method, and Transmission System - It is desired to suitably carry out transmission processing and reception processing carried out when transmitting a multicarrier signal where specific subcarriers are omitted. Therefore, the present invention carries out transmission avoidance processing operable when transmitting a multicarrier signal to replace signals corresponding to subcarriers, in a plurality of subcarriers, at frequency positions where transmission is avoided with a null signal. Subsequently, an inverse Fourier transform is carried out on the output of the transmission avoidance processing, the transmission power of the multicarrier signal that has been transformed is amplified in accordance with the number of subcarriers replaced with the null signal and the multicarrier signal is transmitted. When this multicarrier signal is received, subcarriers where transmission was avoided are estimated, and when it is estimated in the estimation that subcarriers where transmission was avoided are present, despreading and demodulation are carried out without using the subcarriers where transmission was avoided. | 08-20-2009 |
