USAGE OF DISCRETE FREQUENCY SPECTRUM IN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SYSTEM, AND RECEIVING METHOD AND APPARATUS USING DISCRETE FREQUENCY SPECTRUM

摘要

embodiments of the invention are of the discrete frequency spectra in an orthogonal frequency division multiplexing system, used, and a discrete frequency spectrum and discloses a method and apparatus using the reception, this is related to the field of communications, and to improve the utilization of the discrete frequency spectrum. The process according to the invention to produce a single carrier having a bandwidth equal to or greater than the bandwidth of the discrete frequency spectrum to be used; The carrier of the sub-carriers to each sub-step of mapping each of the discrete frequency spectrum; Wherein each sub-sub corresponding to a discrete frequency spectrum to form an X-th carrier signal from the carrier; - Where X is a natural number other than 0 and transmitting the X-th carrier signals to the device using a radio frequency module and. The method can be applied primarily to the use of the discrete frequency spectrum. ;
