摘　　要：多通道信号处理机系统通常包括几十个、上百个发送/接收通道,随着信号通道的增加,系统的体积增大,硬件设计的复杂度也会增加。面对当前日新月异的应用场景和信号处理新技术,通用化和标准化的信号处理机可缩短新系统/新项目的设计、研发以及验证周期,加速新技术验证或投入实际应用。针对上述问题,提出了一种大带宽、多通道的通用信号处理机硬件结构设计,采用3U VPX标准化、微型化和模块化思路,并结合片上射频系统芯片(Radio-Frequency System-on-Chip,RFSoC)完成硬件平台设计,该硬件平台具有8路DAC发射通道和8路ADC接收通道,模拟带宽覆盖0~6 GHz。该设计降低了系统设计的复杂度,使系统规范化、通用化,易于进行扩展使用。通过测试和应用实例,综合验证了该设计的可靠性和可行性。A multi-channel signal processor system usually includes dozens or hundreds of transmit/receive channels.With the increase of signal channels,the volume of the system increases,and the complexity of hardware design also increases.Faced with the current rapidly changing application scenarios and new signal processing technologies,a generalized and standardized signal processor can shorten the design,development and verification cycle of new systems/projects,and accelerate the verification of practical application of new technologies.Given the above problems,the hardware structure design of a large bandwidth,multi-channel general-purpose signal processor is proposed.The idea of 3U VPX standardization,miniaturization and modularization is adopted,and the hardware platform is designed by combining with an RFSoC(Radio-Frequency System-on-Chip).The hardware platform has 8 DAC transmit channels and 8 ADC receive channels,the analog bandwidth covers 0~6 GHz.The complexity of system design is reduced,the system is standardized and generalized,and is easy to scale and use.Through tests and application examples,the reliability and feasibility of the design are comprehensively verified.
