Abstract
This disclosure relates to a system and method for generating single-carrier frequency division multiple access (SC-FDMA) transmissions using a high efficiency architecture. According to some embodiments, frequency resources allocated for a transmission may be determined. The allocated frequency resources may have a bandwidth less than a channel bandwidth of a frequency channel of the transmission, and may be centered around a particular frequency. The frequency may be offset from the center frequency of the channel. A baseband signal located around DC corresponding to the channel center frequency may be generated. The baseband signal may be up-converted to an RF signal using a local oscillator tuned to the frequency around which the allocated frequency resources are centered. The RF signal may be transmitted.
