Abstract
A CDMA signal processing circuit ( ) includes a summer circuit ( ) that receives a plurality of CDMA signals from a plurality of channels ( ). The summer circuit ( ) combines the plurality of CDMA signals according to a power magnitude value and power direction value associated with each CDMA signal. The summer circuit ( ) generates a summed signal ( ) that is applied to a clipping circuit ( ). The clipping circuit ( ) removes a portion of the summed signal ( ) outside a desired threshold range and generates a clipped signal ( ) therefrom. Digital to analog processing circuits ( and ) convert the clipped signal ( ) into a half width encoded format. Digital to analog processing circuits ( and ) transform the half width encoded clipped signal into analog I and Q signals, respectively. The analog I and Q signals are applied to corresponding filters ( and ) prior to transmission.
