H= nrPerfectChannelEstimate(___,,,,toffset)specifies the timing offset in addition to the input arguments in any of the previous syntaxes. The timing offset indicates the OFDM demodulation starting point on the reconstructed waveform.
H= nrPerfectChannelEstimate(___,,,,名称,价值)specifies options by using one or more name-value pair arguments in addition to the input arguments in any of the previous syntaxes.

Data Types:double
nSlot- 插槽号 0(默认)|非负整数
插槽号,指定为非负整数。您可以设置nSlotto a value larger than the number of slots per frame. For example, you can set this value using transmission loop counters in a MATLAB®模拟。在这种情况下,您可能必须确保属性值是调用代码中每个帧数的插槽数。
Data Types:double
循环序列- 循环前缀长度 '普通的'(默认)|'extended'
循环前缀长度,指定为这些选项之一。
'普通的'-Use this value to specify normal cyclic prefix. This option corresponds to 14 OFDM symbols in a slot.
'extended'- 使用此值来指定扩展循环前缀。此选项对应于插槽中的12个OFDM符号。For the numerologies specified in TS 38.211 Section 4.2, extended cyclic prefix length applies for only 60 kHz subcarrier spacing.
Channel path gains of the fading process, specified as annCS-by-np-by-nt-by-nr复杂矩阵,其中:
nCSis the number of channel snapshots.
npis the number of paths.
nt是发射天线的数量。
nr是接收天线的数量。
Data Types:单身的|double 复杂的数字支持:金宝app是的

资源块数量,指定为1到275的整数。
Data Types:double
SCS-khz的子载波间距 15|30|60|120|240
kHz中的子载波间距,指定为15,,,,30,,,,60,,,,120, 或者240。
Data Types:double
pinitialnslot-初始插槽号 非负整数
初始插槽号,,,,0-based, specified as a nonnegative integer. The function selects the appropriate cyclic prefix length for the OFDM demodulation based on the value ofpinitialnslotModulo每个子框架的插槽数。
sampleTimes-Sample times of channel snapshots nCS-by-1 column vector of nonnegative real numbers
通道快照的样本时间,指定为nCS- 非负实数的by-1列矢量。sampleTimes指定每个通道快照的发生时间。频道快照的数量,nCS,,,,is identical to the first dimension ofpathGains。如果未指定,sampleTimes默认为一个nCS-1矢量的时间从零开始,用于OFDM调制资源块数量的采样率nrb和子载波间距SCS。确保通道快照范围至少跨越一个插槽。该函数对每个完整插槽执行通道估计。
Data Types:double
CPL-循环前缀长度 '普通的'(默认)|'extended'
循环前缀长度,指定为以下选项之一:
'普通的'-Use this value to specify normal cyclic prefix. This option corresponds to 14 OFDM symbols in a slot.
如果指定carrierinput, use the循环序列property of thecarrier输入以指定循环前缀长度。您不能将此名称值对参数与carrier输入。
如果您指定带有循环前缀长度CPLinput, you cannot use this name-value pair argument.
Data Types:char|细绳
nfft-FFT点数 integer greater than 127 (default depends on other input values)|[]
number of fast Fourier transform (FFT) points, specified as the comma-separated pair consisting of'Nfft'and a nonnegative integer greater than 127 or[]。您指定的值必须导致整数值循环前缀长度和100%的最大占用率。占用度定义为(12×nRB)/nfft,,,,wherenRBis the number of resource blocks.
