Abstract:
1. An apparatus operable in a wireless communication system for reduced bit-width Code Division Multiple Access (CDMA) Fast Fourier Transform (FFT) in an Orthogonal Frequency Division Multiple Access (OFDMA) transmitter of an access terminal, the apparatus comprising: means for applying a first power signal to at least one of a plurality of CDMA input signals to generate a reduced bit-width CDMA signal; means for summing the plurality of CDMA input signals with the applied power signal; means for performing an FFT on the plurality of CDMA signals; means for applying a second power signal to an OFDMA signal; and means for combining the fast Fourier transformed CDMA signals with the OFDMA signal, wherein the first power signal applied to the CDMA input signal has a reduced bit-width relative to the second power signal applied to the OFDMA signal.
