method of band limiting for IFDMA commnuication system

摘要

A method for band limiting in a Single Carrier Frequency Division Multiple Access (SC-FDMA) communications system comprises generating a SC-FDMA data symbol block and band-limiting the SC-FDMA data symbol block using a window (309). A transmitter in a SC-FDMA communications system comprises a SC-FDMA data symbol block generator which generates a SC-FDMA data symbol block and a window (309) for band limiting the SC-FDMA data symbol block. Using a window (309) for band limiting has an advantage to decrease the number of calculations because only multiplication's between the transmitted signal and the window (309) are required.
