Original Abstract Submitted
Certain aspects of the present disclosure provide techniques for digital pre-distortion (DPD). An apparatus for wireless communication generally includes a power amplifier (PA); a first DPD circuit, a second DPD circuit, and a transmitter. The first DPD circuit is generally configured to: obtain an input signal; apply a first DPD to the input signal to generate a first resulting signal; and output the first resulting signal to the second DPD circuit. The second DPD circuit is generally configured to: obtain the first resulting signal from the first DPD circuit; apply a second DPD to the first resulting signal to generate a second resulting signal; and output the second resulting signal to the PA. The PA is generally configured to amplify the second resulting signal to generate an amplified second resulting signal. The transmitter is generally configured to transmit the amplified second resulting signal to a second apparatus.
