Abstract
Transmission data that will be transmitted is coded and thus band-spread using a spread code. The band-spread transmission data is also coded using a scrambling code. The scrambling process is followed by pulse shaping, frequency correction, and DC offset and/or amplitude compensation for the band-spread and scrambled transmission data.
