nrPerfectChannelEstimate
Perfect channel estimation
Syntax
Description
performs perfect channel estimation. The function first reconstructs the channel impulse
response from the channel path gains h
= nrPerfectChannelEstimate(carrier
,pathGains
,pathFilters
)pathGains
and the path filter
impulse response pathFilters
. The function then performs orthogonal
frequency division multiplexing (OFDM) demodulation. carrier
specifies
the parameters for the OFDM demodulation.
performs the OFDM demodulation for h
= nrPerfectChannelEstimate(pathGains
,pathFilters
,nrb
,scs
,initialNSlot
)nrb
number of resource blocks with
subcarrier spacing scs
and initial slot number
initialNSlot
.
specifies the sample times of the channel snapshots in addition to the input arguments in
the previous syntax.h
= nrPerfectChannelEstimate(___,toffset
,sampleTimes
)
specifies options by using one or more name-value pair arguments in addition to the input
arguments in any of the previous syntaxes.h
= nrPerfectChannelEstimate(___,Name,Value
)
Note
The function limits the timing offset to the CP length. To synchronize the channel
impulse response to the start of the useful part of the OFDM symbols when the
toffset
input exceeds the specified CP length
(cpl
, CyclicPrefix
, or
carrier
.CyclicPrefix
), the function shortens
the specified path filter impulse response, pathFilters
.
