摘　　要：在短距离窄带无线通信系统中,具有结构简单、低成本、低功耗和灵敏度较高(相对于再生接收机)等优点的超再生接收机已经有几十年的应用历史。这里,根据超再生的基本原理,构建出一种用于对直序列扩频(DS-SS)信号进行非相干检测的扩频接收机的新型结构,并对其在2.4GHz的ISM波段的宽带应用进行分析。In short-range narrowband communications, the super-regenerative receiver has been used for many decades, it has much advantages, such as simple-structure, low-cost, low-power consumption and high sensitivity（to be compared to regenerative receiver）, etc; In this paper, according to the super-regenerative principle, a new architecture of the receiver is presented to use in non-coherent detection of direct-sequence spread-spectrum signals, and the analysis is given for it to be applied to 2.4GHz ISM band in broadband applications.
