Ideal Channel Realization#

class IdealChannelRealization(alpha_device, beta_device, gain, interpolation_mode=InterpolationMode.NEAREST)[source]#

Bases: ChannelRealization

Realization of an ideal channel.

Generated by the realize() routine of IdealChannels.

Parameters:

  • alpha_device (Device) – First device linked by the Channel instance that generated this realization.

  • beta_device (Device) – Second device linked by the Channel instance that generated this realization.

  • gain (float) – Linear power gain factor a signal experiences when being propagated over this realization.

  • interpolation_mode (InterpolationMode, optional) – Interpolation behaviour of the channel realization’s delay components with respect to the proagated signal’s sampling rate.

state(transmitter, receiver, delay, sampling_rate, num_samples, num_taps)[source]#

Generate the discrete channel state information from this channel realization.

Denoted by

\[\mathbf{H}^{(m, \tau)} \in \mathbb{C}^{N_{\mathrm{Rx}} \times N_{\mathrm{Tx}}}\]

within the respective equations.

Parameters:

  • transmitter (Device) – Device transmitting the signal for which the channel state information is generated.

  • receiver (Device) – Device receiving the signal for which the channel state information is generated.

  • delay (float) – Delay in seconds at which the state information should be generated.

  • sampling_rate (float) – Sampling rate of the state information’s discrete samples in \(\mathrm{Hz}\).

  • num_samples (int) – Number of discrete time-domain samples of the chanel state information.

  • max_num_taps (int) – Maximum number of delay taps considered per discrete time-domain sample.

Return type:

ChannelStateInformation

Returns: The channel state information representing this channel realization.
