Notes/Equations
- This subnetwork is used to measure the complementary cumulative distribution function (CCDF) according to the input signals.
The schematic for this subnetwork is shown in the following figure.
WCDMA3G_CCDF Schematic
- Each firing, BurstLen × BurstNum signals are input (BurstLen is the length of slot and BurstNum is the number of slots to be measured). WCDMA3G_DisFunc measures the distribution function according to input signal power; results are collected by four NumericSink components. The distribution range is sent to the NumericSink identified as SignalRange and is divided into segments according to OutputPoint. The corresponding distribution probability is calculated based on these segments and sent to the NumericSink identified as CCDF.
WCDMA3G_DisFunc calculates peak power of 99.9% probability and average power of input signals. These results are collected by the NumericSinks identified as PeakPower and MeanPower.
Note that PeakPower, MeanPower and SignalRange units are dBm; SignalRange is the absolute signal power minus MeanPower.
Typical simulation results are shown in the following figure.
