  • System and method to adjust searcher threshold parameter of rake receiver
    Publication number: 20030165132
    Abstract: This present invention is a system and method to adjust a searcher threshold parameter of a RAKE receiver. The adjusting system includes a searcher, a power estimator, and a parameter control apparatus. When the searcher finds and acquires a new path signal, the power estimator will estimate the power of the new path signal and that of the other path signals. The parameter control apparatus will calculate and monitor the power ratio corresponding to the new path signal. If the power ratio remains smaller than a predetermined power ratio parameter for a first predetermined times, the parameter control apparatus will increase the value of the threshold parameter. If the power ratio remains unchanged for a second predetermined times, the parameter control apparatus will lower the value of the threshold parameter. After that, the searcher will acquire the path signals among the multipath signal being searched in accordance with the adjusted threshold parameter.
