5.2.4 Reception characteristics

Noise floor: define a distribution of the noise floor

N

Distribution or Scalar

dBm

See section 1.2.3 for further details

Blocking mode

-

Boolean

-

Blocking mode and associated blocking mask

Blocking response: Receiver frequency response (receiver blocking performance)

blocking

Function (X,Y)

(MHz)

dBm or dB depend. on mode

Receiver mask attenuation (positive or negative values depending on the chosen blocking mode, see below) versus frequency, see ANNEX 8:

Intermodulation rejection: Intermodulation response (intermodulation interference)

intermod

Function (X,Y)

(MHz)

dB

Receiver mask at the intermodulation frequency. (see Annex A5.3 for further details)

Receive power dynamic range

Pc_max

Scalar

dB

Used in the calculation of the dRSS. It is the maximum range of the received power that the VLR can accept, in terms of the maximum receive power over the VLR’s sensitivity threshold.

If the trialled dRSS value exceeds sens+Pc_max , the dRSS is set to the latter value. See ANNEX 14:.

Sensitivity

sens

Scalar

dBm/VLR reception bandwidth

Sensitivity of the receiver. See Section 1.2.4

Reception bandwidth: Operating bandwidth

B

Scalar

kHz

Bandwidth of the receiver.

Overloading

-

Boolean

-

When selected, the overloading calclulation is performed. See Annex A5.4 for further details.

Overloading threshold

Oth

Function (X,Y)

(MHz)

dBm

It is the maximum interfering signal level close to which  the receiver loses its ability to discriminate against interfering signals at frequencies differing from that of the wanted signal

Receiver filter

Rx_filter

Function (X,Y)

(MHz)

dB

Filtering of the receiver (if any). The filtering of the receiver is by default 0 dB (similarly to the default blocking filtering value). It is used in connection with the overloading calculation.
