Abstract

The invention discloses a wideband waveform generating component and method. The component includes: an FPGA programmable logic processor, a high-speed ADC and a high-speed DAC; the FPGA programmable logic device is used to receive an external control signal and an input signal of the high-speed ADC. The sampled data is generated in real time according to the input control signal, and is converted into a serial signal after being distorted and filtered to be output to the high-speed DAC, and the high-speed DAC outputs a broadband waveform signal after digital-to-analog conversion. The invention realizes a multi-channel parameterized waveform generation module, a predistortion filter module and a filter coefficient calculation module in the FPGA programmable logic device, which can not only generate a wideband linear frequency modulation waveform with arbitrary bandwidth and pulse width in real time and parameterization, but also The pre-distortion can be adaptive to improve the pre-distortion efficiency of the component.

Description

technical field [0001] The present invention relates to the field of communications, and more particularly, to a wideband waveform generating component and method. Background technique [0002] Existing broadband waveform generation components can only output broadband waveforms with a specific bandwidth and pulse width, and when performing amplitude and phase predistortion, other equipment needs to be used to record the transmitted waveform, calculate the distortion characteristics and store them. When the consistency of the amplitude and phase characteristics is poor, it is necessary to repeatedly record and calculate, which is time-consuming and labor-intensive. SUMMARY OF THE INVENTION [0003] In order to solve at least one of the technical problems raised in the background art, one object of the present invention is to provide a wideband waveform generation component and method, the wideband waveform generation component includes: an FPGA programmable logic processor...
