摘要： Disclosed are an apparatus for transmitting multi-carrier signals, including: a signal spreading unit configured to generate band-spread signals through band spreading of a plurality of symbol-mapped signals; and a modulation unit configured to generate a modulation signal by mixing the band-spread signals with a plurality of sub-carriers and adding up the mixed band-spread signals, and a method for transmitting multi-carrier signals.
