class kaira.models.image.Tung2022DeepJSCCQ2Decoder(N: int, M: int, out_ch: int = 3, csi_length: int = 1, *args: Any, **kwargs: Any)[source]

Bases: BaseModel

DeepJSCCQ2 Decoder Module [Tung et al., 2022].

This module is from the conference paper, not the journal version. Note that this module is different than DeepJSCCQ, which contains 4 strided layers and does not contain the AFModule.

This module decodes a latent representation into an image using a series of convolutional layers and AFModules.

Methods

__init__

Initialize the DeepJSCCQ2Decoder.

forward

Forward pass through the decoder.

from_config

Create model instance from configuration.

from_hydra_config

Create model from Hydra DictConfig.

from_pretrained_config

Create model from Hugging Face PretrainedConfig.

Attributes

bandwidth_ratio

Calculate the bandwidth ratio of the model.
__init__(N: int, M: int, out_ch: int = 3, csi_length: int = 1, *args: Any, **kwargs: Any) → None[source]

Initialize the DeepJSCCQ2Decoder.

Parameters:

  • N (int) – The number of channels in the input and output feature maps of the neural network.

  • M (int) – The number of input channels for the AttentionBlock and ResidualBlock modules.

  • out_ch (int, optional) – The number of output channels. Defaults to 3.

  • csi_length (int, optional) – The number of dimensions in the CSI (Channel State Information) data.

  • *args – Variable positional arguments passed to the base class.

  • **kwargs – Variable keyword arguments passed to the base class.

property bandwidth_ratio: float
