How to Determine Base Station Threshold Received Power Adaptive to Fading Environment Change

摘要

1. TECHNICAL FIELD OF THE INVENTION;A method for determining the base station threshold reception power adaptive to fading environment changes.;2. The technical problem to be solved by the invention;The frame error rate is improved by varying the unit increase / decrease to suit the change characteristic of the partial average value of the Eb / No threshold due to the change in the fading environment.;3. Summary of Solution to Invention;Checking a partial mean value change state of a received power-to-noise ratio (Eb / No) threshold value according to a result of comparing a threshold value of a current error frame with a previous error frame threshold; Increasing the increase of the threshold value if the partial mean value is increased, and maintaining the decrease of the threshold value as it is; Maintaining an increase amount of the threshold value and increasing the decrease amount of the threshold value when the change state of the partial mean value is reduced; Reducing both the increase and decrease of the threshold value if the change in the partial mean value is an increase-decrease state or a decrease-increase state; If there is no change in the partial mean value, the step of setting the increment and decrement of the threshold value to the initial unit increment.;4. Important uses of the invention;Used for base station controller of CDMA mobile communication system.
