摘要：The present invention discloses a digital pre-distortion circuit capable ofcompensating an analog circuit for its non-linear characteristic. An embodiment of saiddigital pre-distortion circuit comprises: a pre-distortion training circuit and a pre-
distortion circuit. Said pre-distortion training circuit is operable to process a digitalfeedback signal according to a Cholesky Decomposition related algorithm and therebygenerate a plurality of coefficients in which the digital feedback signal is derived from anoutput signal of the analog circuit and the output signal of the analog circuit is derivedfrom an original digital signal; and said pre-distortion circuit is operable to process theoriginal digital signal according to the plurality of coefficients under a compensationmode and thereby generate a digital pre-distortion signal whose non-linear characteristicis able to compensate the non-linear characteristic of the analog circuit.
