MCSDecoder

class sionna.phy.utils.MCSDecoder(*args: Any, precision: Literal['single', 'double'] | None = None, device: str | None = None, **kwargs: Any)

Bases: sionna.phy.block.Block

Class template for mapping a Modulation and Coding Scheme (MCS) index to the corresponding modulation order, i.e., number of bits per symbol, and coderate.

Inputs:

• mcs_index – […], torch.int32. MCS index.

• mcs_table_index – […], torch.int32. MCS table index. Different tables contain different mappings.

• mcs_category – […], torch.int32. Table category which may correspond, e.g., to uplink or downlink transmission.

• check_index_validity – bool. If True, a ValueError is thrown if the input MCS indices are not valid for the given configuration. Defaults to True.

Outputs:

• modulation_order – […], torch.int32. Modulation order corresponding to the input MCS index.

• coderate – […], torch.float. Coderate corresponding to the input MCS index.

Parameters:

• args (Any)

• precision (Literal['single', 'double'] | None)

• device (str | None)

• kwargs (Any)
