dialog's tab, you can set the parameters for theWhen the LTE Demodulator will find and analyze the Positioning Reference Signal according to the following parameters.
check box is selected, theDetermines the frequency width of the P-RS in units of resource blocks. This frequency band is centered in frequency with respect to the LTE frame.
All possible P-RS bandwidths are available for selection, but if you select a P-RS bandwidth larger than the current LTE frame bandwidth, the P-RS bandwidth will be limited to the maximum possible once you click
to close this dialog.P-RS power boost (see description of Basic tab topic) determines the power of P-RS relative to the 0 dB point of the LTE frame.
parameters inThe Configuration Index specifies the value of IPRS in the standard and is used to determine the periodicity and starting subframe of the P-RS from Table 6.10.4.3-1 in TS 36.211.
When the frame number is known (PBCH decoding enabled), the LTE demodulator can determine the exact frame/subframes that contain P-RS. In this case, the demodulator will expect P-RS in these frames and report bad EVM when P-RS is not found. P-RS found in non-P-RS frames will also be reported as bad EVM.
When the frame number is not known (PBCH decoding disabled), the LTE demodulator will search for P-RS in any potential P-RS subframes and analyze P-RS only when found.
Number of contiguous subframes allocated for P-RS.
Possible selections are N1, N2, N4, and N6 indicating 1, 2, 4, and 6 subframes, respectively.
When the MBMS signals (PMCH and MBSFN-RS) according to the following parameters.
check box is selected, the LTE Demodulator will find and analyzeSpecifies the value of NMBSFNID which is used to determine the MBSFN-RS reference sequence.
Possible values are in the range 0-255.
Specifies the number of symbols at the beginning of an MBSFN subframe that are not used for MBSFN transmissions.
Possible values are 1 or 2.
MBSFN-RS power boost (see description of Basic tab topic) determines the power of MBSFN-RS relative to the 0 dB point of the LTE frame.
parameters inDetermines which subframes are possible MBSFN subframes. The behavior of MBSFN-RS analysis is different depending on whether RB Auto Detect is enabled.
The PMCH section appears differently depending on whether is selected or not.
This parameter appears when
is selected.These parameters are used to manually configure PMCH (RB Auto Detect is not selected) for the possible MBSFN subframes.
