    摘要: An apparatus and method for measuring the quality of a reverse link and the load of a base station (BTS) in a CDMA mobile telecommunication system. The apparatus and method periodically detect the power of a receiving signal from a mobile station to a BTS, constructs a practical statistical distribution curve for a power ratio of signal to interference, compares the practical distribution curve with the theoretical distribution curve pre-constructed based upon the parameter condition of a BTS, and determines the quality of a reverse link based upon the difference between the distribution curves. The link-quality measuring device has a power detecting unit for detecting the power of signals received by a BTS; a converter for digitizing the detected power; a controlling unit constructing a PDF (Probability Density Function) and/or a CDF (Cumulative Distribution Function) for a ratio of a received power to a background noise power using the digitized data, comparing the constructed function with the theoretical PDF and/or CDF for the ratio which is pre-calculated based upon various values of input parameters, and acquiring the traffic load according to the compared result; and data entering unit for receiving the values for the input parameters provided from an operator or an external device.
