The multiplier calculates the product of amplitudes or the product of power of transmission signals at two different times or calculates the ratio of amplitudes or the ratio of power of transmission signals at two different times. The subtracter calculates the phase difference between the transmission signals at two different times. The LUT specifies a distortion compensation coefficient by using both the product or the ratio calculated by the multiplier and the phase difference calculated by the subtracter. The distortion compensation unit performs, by using the distortion compensation coefficient specified by the LUT, a predistortion process on the transmission signal that is input to the amplifier."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Distortion compensation device and distortion compensation method","description":"A distortion compensation device includes a multiplier, a subtracter, an LUT, and a distortion compensation unit.
