Processing CDMA signals

A method of processing CDMA signals, comprising:

• performing a spreading function on CDMA signals from a plurality of channels;
• combining the CDMA signals of the plurality of channels to create a digital summed signal, the digital summed signal being a combination of power values of each CDMA signal;
• removing a portion of the digital summed signal above and below a desired threshold range to create a clipped signal;
• converting the clipped signal into separate in-phase and quadrature phase data channels for modulating a radio frequency carrier transmission signal, the in-phase and quadrature phase data channels carrying information in a half-width pulse configuration, wherein a first half of the pulse contains valid information and a second half of the pulse has a return to zero format.

An apparatus for processing CDMA signals, comprising:

• a summer circuit operable to combine CDMA signals from a plurality of channels, the summer circuit operable to generate a digital summed signal therefrom, the digital summed signal being a combination of power values of each CDMA signal;
• a clipping circuit operable to remove a portion of the digital summed signal above and below a desired threshold range, the clipping circuit operable to generate a clipped signal therefrom;
• a digital to analog processing circuit operable to convert the clipped signal into a half width encoded format, the half width encoded format having information contained in a first half of a signal pulse and no information in a second half of the signal pulse, the digital to analog processing circuit operable to convert the clipped signal in the half width encoded format to an analog signal;
• a filter operable to reduce inter-symbol interference in the analog signal.
