Method and apparatus for measuring signal interference ratio

Abstract

Signals are picked up according to certain time slot format. Signal power is calculated for different signals. Signal powers are filtered by using different filtering factor so as to obtain their estimated value. Time slot measured value of signal interference ratio (SIR) is calculated based on the said power estimated value. The said measured value is modified by reference of the reception characteristics of real receiving hardware subsystem. According to given measuring period, statistical average is carried out for the modified measured values so as to obtain SIR within a measuring period. Proper modification is carried out for result of measuring SIR in order to give more accurate result in whole measuring range. The invention provides more accurate, detailed and reliable reference for wireless resource management such as power control.

Problems solved by technology

However, there is a problem in the existing SIR measurement methods, that is, the SIR measurement module is independent of other hardware processing parts of the receiver, and only the relevant analysis, processing and implementation are carried out from the perspective of the SIR measurement algorithm itself, while for the SIR measurement module The ability to adapt to the receiving part of the actual system hardware has not been deeply analyzed and further discussed

However, an unavoidable problem in SIR measurement is that the SIR measurement module must adapt to the receiving characteristics of its own receiver subsystem in order to give more accurate, reliable and effective measurement results

This method is relatively new, but the method of using related functions to solve the Doppler bandwidth has a large amount of calculation, and the complexity of hardware implementation is relatively high.
