A method and apparatus for data transmission are provided. Data values of a plurality of channels are transformed into a transmission signal. An enhanced shaping filter is provided to shape a binary stream of only single digits and generate a shaped signal. A weighting unit is coupled to the output of the shaping filter, weighting the shaped signal to effectively generate a quality baseband signal. The binary stream is converted from the data values through spreading and scrambling. A scrambling unit, scrambles the binary stream with scrambling codes. A spreading unit spreads the binary stream at a chip rate before sending the binary to the scrambling unit.
