Embodiment Construction

[0051] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0052] Such as figure 1 As shown, a high-speed parallel signal processing method includes a data sending step S1 and a data receiving step S2:

[0053] The data sending step S1 includes:

[0054] S101. The source generates digital signal x of N-substrate band 1 (n), x 2 (n),...,x N (n), transmitted to the digital domain baseband signal processing module at the sending end, each signal contains n data, where n>>N and n is an integer multiple of N;

[0055] S102. Utilize the baseband signal processing module in the digital domain of the sending end to process the baseband digital signal x of N channels 1 (n), x 2 (n),...,x N (n) to process and get N-way data y 1 (1),y 1 (2),...,y 1 (n), y 2 (1),y 2 (2),...,y 2 (n),...,y N (1),y N...

Abstract

The invention discloses a high-speed parallel signal processing method and device, including the data sending step S1: S101. Information source generation N Roadbed digital signal; S102. Sending end digital domain baseband signal processing module pair N Process the subgrade with digital signals to obtain N sets of data; S103. Perform buffering and data conversion processing on each set of data; S104. Use N-channel DAC to perform digital-to-analog conversion on each set of converted data, and pass through in different phases The signal sending module sends; the data receiving step S2 includes: S201. The data received by the N-channel ADC is analog-to-digital converted, and transmitted to the data buffer conversion module of the receiving end; S202. The data buffer conversion module of the receiving end converts the received data Perform buffering and conversion processing; S203. The digital domain baseband signal processing module at the receiving end processes the converted data to obtain N-channel baseband signals and transmit them to the sink. Each channel of the present invention processes data independently without being affected by other channels, thereby reducing the complexity of processing.

Description

technical field [0001] The invention relates to parallel signal processing, in particular to a high-speed parallel signal processing method and device. Background technique [0002] With the gradual exhaustion of low-frequency spectrum resources, the working frequency band of wireless communication is developing into the terahertz frequency band, and the communication rate is getting higher and higher. Therefore, the digital baseband system is required to generate signals with larger bandwidth and higher order modulation, and to carry higher data volumes. Restricted by the operating frequency of the system core (such as FPGA), high-speed signal processing mostly adopts multi-channel parallel processing. [0003] However, at present, the traditional parallel signal processing method has high complexity, and the signal processing of each channel is affected by other channels, which brings a lot of inconvenience to the transmission and processing of parallel signals.
