comnum.mimo_channels#

comnum.mimo_channels(n, n_rx, n_tx, rng, *, k_factor=0.0, rx_correlation=Ellipsis, tx_correlation=Ellipsis)#

Independent flat MIMO channel matrices, one per channel use, as mimo_channel().

Parameters:

  • n (int) – number of matrices.

  • n_rx (int) – receive antennas.

  • n_tx (int) – transmit antennas.

  • rng (Rng) – the generator.

  • k_factor (float) – Rician factor K (linear, 0 for Rayleigh).

  • rx_correlation (complex) – correlation ρ of adjacent receive antennas.

  • tx_correlation (complex) – correlation ρ of adjacent transmit antennas.

Returns:

(n, n_rx, n_tx) (complex128).

Return type:

numpy.ndarray

Raises:

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

>>> import comnum
>>> comnum.mimo_channels(10, 4, 2, comnum.Rng(1)).shape
