Abstract:
1. A method for acquiring multi-band digital pre-distortion (DPD) output signals, comprising: receiving at least two input signals in different working frequency bands; determining DPD coefficients corresponding to the input signals currently received in the respective working frequency bands, wherein a DPD coefficient corresponding to an input signal currently received in any working frequency band is obtained according to feedback signals of respective input signals previously received in the respective working frequency bands and an input signal previously received in the any working frequency band; and acquiring DPD output signals corresponding to the input signals currently received in the respective working frequency bands respectively according to the input signals currently received in the respective working frequency bands and their corresponding DPD coefficients, and input signals currently received in interfering frequency bands of the respective working frequency bands.
