Perfect Channel Estimate
Estimation of the ideal channel.
Description
The Perfect Channel Estimate block performs channel estimation by reconstructing the channel impulse response based on the parameters of the block and then performing OFDM demodulation.
Parameters
Carrier
#
NCellID —
physical layer cell identifier
Real number
Details
A physical layer cell identifier specified as an integer from 0 to 1007.

#
NSizeGrid —
number of remote objects in the telecom operator’s resource table
Real number
Details
The number of remote objects in the service provider’s resource table, specified as an integer from 1 to 275. The by default value of 51 corresponds to the maximum number of resource blocks for a 10 MHz carrier and a subcarrier spacing of 15 kHz.

#
Subcarrier spacing (kHz) —
subcarrier spacing in kHz
15 | 30 | 60 | 120
Details
Subcarrier spacing in kHz for all channels and carrier reference signals.
Selectable values: 15 or 30 for FR1, 60 or 120 for FR2.

#
CyclicPrefix —
cyclic prefix length
Normal | Extended
Details
The length of the cyclic prefix. Options to choose from:
-
Normal- Use this value to specify a normal cyclic prefix. This parameter corresponds to 14 OFDM characters in a slot. -
Extended- use this value to specify an extended cyclic prefix. This parameter corresponds to 12 OFDM characters in the slot. For the numbering specified in the standard [1] in section 4.2, the extended cyclic prefix length applies only for 60 kHz subcarrier spacing.
