Table 2 RSRP descriptors
From: CSI-based fingerprinting for indoor localization using LTE Signals
Descriptor | Formula | Description |
|---|---|---|
Mean | \(\mu = \frac {1}{N_{\text {SLOT}}}\sum \limits _{s=0}^{N_{\text {SLOT}}-1} \text {RSRP}[s]\) | The arithmetic mean of the RSRP. |
Standard deviation | \(\sigma = \sqrt {\frac {1}{N_{\text {SLOT}}-1}\sum \limits _{s=0}^{N_{\text {SLOT}}-1} (\text {RSRP}[s] - \mu)^{2}}\) | The standard deviation of the RSRP. |
Fano factor | \(\text {FF} = \frac {\sigma ^{2}}{\mu }\) | The ratio between the variance of the RSRP and its arithmetic mean. |
