摘要
提出基于实时能量估计的码捕获自适应门限调整方法,给出了任意L次独立观测时虚警概率和检测概率的表达式。理论分析和计算机仿真结果表明:此方法的虚警概率恒定,比MLAP和0SAP等恒虚警检验方法的性能优越,且适用于多径误落信道条件下的RAKE接收。
Adaptive DS code acquisition threshold decision based on energy estimation in Real-tune is presented in the article, and its expression for detection and false alarm probability under L observation are given in the following. Its false alarm probability is constant with better performance than MLAP and OSAP and can be used in multi-path fading channel, which has been proved by theoretical analysis and computer simulations.
