SIR measure method and apparatus for the same |
摘要 |
The invention discloses a signal-to-interference ratio (SIR) measurement method. The method measures interference power (I) of a single-path signal after the received signal is demodulated by the single-path demodulators of multipath receiving device at the receiving end. The total interference power is obtained by equipartition combining with the measured interference power of each single-path signal. The signal power (S) is obtained by measuring after maximum ratio combination of each single-path signal. The SIR of the received signal is the division of the signal power and the total interference power. An apparatus, implementing mentioned method, sets the interference power measurement-device in the RAKE combiner and the signal power measurement-device after the RAKE combiner. In this way, the interference measurement can effectively provide more information and can more really response to the channel variation.
