In addition to peak to average power ratio or PAPR detection techniques, an algorithm or process is implemented that uses a transmitted reference packet, such as an orthogonal frequency domain multiplexing (OFDM) packet. The reference packet is used to learn the linear response of a detector that measures output of the power amplifier. The transmitted packet can include a linear response. The included linear response can determined by subtracting a normal packet from the reference packet."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Close-loop power transmission calibration","description":"A close-loop power calibration algorithm is performed on a wireless communication device to correct power amplifier pre-distortion or PADR correction curves.
