Space-Time Block Coding
- class SpaceTimeBlockCoding
Bases:
MaximumRatioCombining,SerializableA precoder distributing symbols in space and time.
Cool.
Space-Time Block Coding object initialization.
- yaml_tag: str = 'STBC'
YAML serialization tag.
- encode(symbols)
Encode data into multiple antennas with space-time/frequency block codes
Currently STBCs with 2 or 4 transmit antennas are supported, following 3GPP TS 36.211, Sec, 6.3.3.3)
- Parameters
symbols (StatedSymbols) – Input signal featuring \(K\) blocks.
Returns: Encoded data with size \(N_tx \times K\) symbols
- Return type
- decode(symbols)
Decode a data stream before reception.
This operation may modify the number of streams as well as the number of data symbols per stream.
- Parameters
symbols (Symbols) – Symbols to be decoded.
Returns: Decoded symbols.
- Raises
NotImplementedError – If an encoding operation is not supported.
- Return type
- property num_input_streams: int
Required number of input symbol streams for encoding / number of resulting output streams after decoding.
- Returns
The number of symbol streams.
- Return type
int
- property num_output_streams: int
Required number of input symbol streams for decoding / number of resulting output streams after encoding.
- Returns
The number of symbol streams.
- Return type
int
- classmethod to_yaml(representer, node)
Serialize a SpaceTimeBlockCoding precoder to YAML.
- Parameters
representer (SafeRepresenter) – A handle to a representer used to generate valid YAML code. The representer gets passed down the serialization tree to each node.
node (SpaceTimeBlockCoding) – The SpaceTimeBlockCoding instance to be serialized.
- Returns
The serialized YAML node.
- Return type
Node
- classmethod from_yaml(constructor, node)
Recall a new SpaceTimeBlockCoding precoder from YAML.
- Parameters
constructor (SafeConstructor) – A handle to the constructor extracting the YAML information.
node (Node) – YAML node representing the SpaceTimeBlockCoding serialization.
- Returns
Newly created SpaceTimeBlockCoding instance.
- Return type
