一种并行结构射频信号生成方法
摘要：
本发明涉及一种并行结构射频信号生成方法，所述方法包括：根据所要生成的射频信号的中心载波频率fc和信号双边带宽BW确定时钟频率fis和采样频率8×fis；根据所述中心载波频率fc和所述时钟频率fis计算载波频率fif；根据所述载波频率fif确定基带数据data的形式；根据所述载波频率fif和所述时钟频率fis生成8路并行载波信号；根据所述8路并行载波信号和所述基带数据data生成四路并行数据；对所述四路并行数据进行数模转换，生成所述射频信号。
摘要（英）：

The invention relates to a method for generating a radio frequency signal of a parallel structure, and the method comprises the steps: determining a clock frequency fis and a sampling frequency 8*fisaccording to the central carrier frequency fc of a to-be-generated radio frequency signal and a signal bilateral bandwidth BW; calculating the carrier frequency fif according to the central carrier frequency fc and the clock frequency fis; determining the form of baseband data according to the carrier frequency fif; generating 8 parallel carrier signals according to the carrier frequency fif and the clock frequency fis; generating four pieces of parallel data according to the 8 parallel carrier signals and the baseband data; carrying out the data conversion of the four pieces of parallel data,and generating a radio frequency signal.
