| titleOfInvention | Blind multi-band signal predistortion method based on compressive sampling structure |
| abstract | The invention discloses a blind multiband signal predistortion method based on a compressive sampling structure, wherein multi-frequency output is used as a broadband signal to carry out down-conversion, the broadband signal is sent to a low-pass filter to filter out part of distortion, an A-MWC sampling structure carries out compressive sampling on the signal, a new underdetermined equation with the observation vector length being twice as long as that of an observation vector of a traditional MWC structure is constructed by utilizing a power spectral density function, and then a variable step length sparsity self-adaptive matching pursuit algorithm (VSStoSAMP) selected based on random support is used for successfully reconstructing a support set of the signal without depending on signal prior information. Compared with the traditional parallel multi-frequency DPD structure, the structure provided by the invention reduces the bandwidth of a feedback loop, obviously reduces the sampling rate of an ADC (analog-to-digital converter), greatly reduces the complexity of the system and reduces the cost. |
