comnum.nr_ssb_grid(n_cell_id, i_ssb_bar=0, *, pbch=None)#

The SSB of a cell: the PSS and the SSS of unit amplitude, the PBCH DMRS and the 432 PBCH symbols.

Parameters:

  • n_cell_id (int) – the cell identity, 0 to 1007.

  • i_ssb_bar (int) – the SSB index ī_SSB, 0 to 7.

  • pbch (array_like | None) – the 432 PBCH symbols (zeros when None).

Returns:

the grid, shape (240, 4) (complex128).

Return type:

numpy.ndarray

Raises:

ValueError – for an invalid parameter or input (the message names it).
