Delay Channel Realization#
- class DelayChannelRealization(alpha_device, beta_device, gain, delay, model_propagation_loss, interpolation_mode)[source]#
Bases:
ChannelRealization
Realization of a delay channel model.
Generated from
DelayChannel's
realize
routine.- Parameters:
alpha_device (Device) – First device linked by the
DelayChannel
instance that generated this realization.beta_device (Device) – Second device linked by the
DelayChannel
instance that generated this realization.gain (float) – Linear power gain factor a signal experiences when being propagated over this realization.
delay (float) – Propagation delay in seconds.
model_propagation_loss (bool) – Should free space propagation loss be modeled?
- state(transmitter, receiver, delay_offset, sampling_rate, num_samples, max_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:
Returns: The channel state information representing this channel realization.
- to_HDF(group)[source]#
Serialize the object state to HDF5.
Dumps the object’s state and additional information to a HDF5 group.
- Parameters:
group (h5py.Group) – The HDF5 group to which the object is serialized.
- Return type:
