摘要
为了在保证传统DS-SS宽带接受机性能指标的基础上进一步降低接收机的复杂度,将超再生技术运用于对直序列扩频信号非相干检测的宽带扩频接收机的设计中,并对其在2.4GH z的ISM波段的宽带应用进行分析,结果表明,本接收机具有良好的性价比。
In order to reduce the complexity of broadband receiver in a DS-SS system without any prejudice to its performance, we propose that super-regenerative technique be applied to the design of broadband receiver used in detecting direct-sequence spread-spectrum signals. An analysis has been made before it is applied to 2.4GHz ISM band in broadband application. The results prove that the receivers of this design are excellent both in performance and cost.
