Stream Precoding#

Stream precodings implement MIMO algorithms on a base-band signal sample level during both signal transmission and reception.

class ReceiveStreamCoding(modem=None)[source]#

Bases: Precoding[ReceiveStreamDecoder], Serializable

Stream MIMO coding configuration during signal transmission.

Symbol Precoding object initialization.

Parameters:: modem (Modem, Optional) – The modem this Precoding configuration is attached to.

decode(signal)[source]#

Decode a signal MIMO stream during reception.

This operation may modify the number of streams.

Parameters:: streams (Signal) – The signal stream to be decoded.
Return type:: Signal

Returns: The decode signal stream.

yaml_tag: Optional[str] = 'ReceiveCoding'#: YAML serialization tag.

class ReceiveStreamDecoder[source]#

Bases: Precoder, ABC

Stream MIMO coding during signal reception.

abstract decode_streams(streams)[source]#
