Ettus X410

Note

These presets are currently under active development and may still contain inaccuracies.

Implementation of a block-based radio-frequency front-end model following the datasheet of Ettus’ USRP X410 software-defined radio. It can be used within a simulation-context by assigning it as a simulated device’s rf chain model:

scenario = SimulationScenario(seed=42)
for _ in range(2):

    # Add a new device
    device = scenario.new_device(
            carrier_frequency=cf,
            bandwidth=nr_bandwidth(numerology=0),
            oversampling_factor=3,
            rf=X410(
                carrier_frequency=cf,
                tx_gain=dB(35),
                rx_gain=dB(10),
            ),
            antennas=SimulatedUniformArray(
                SimulatedIdealAntenna(AntennaMode.DUPLEX),
                .1,
                [1, 1, 1],
            ),
        )

# 3GPP Urban Macrocell channel model
channel = UrbanMacrocells(expected_state=O2IState.LOS)
scenario.set_channel(scenario.devices[0], scenario.devices[1], channel)
scenario.devices[0].trajectory = StaticTrajectory(Transformation.From_Translation([0, 0, 6]))
scenario.devices[1].trajectory = StaticTrajectory(Transformation.From_Translation([50, 50, 1.5]))

# Downlink with a single NR slot
slot = NRSlot()
slot.channel_estimation = OrthogonalLeastSquaresChannelEstimation()
slot.channel_equalization = OrthogonalZeroForcingChannelEqualization()

link = SimplexLink(
    selected_transmit_ports=[0],
    selected_receive_ports=[0],
    waveform=slot,
)
link.connect(scenario.devices[0], scenario.devices[1])

Bases: RFChain

Model of an Ettus X410 USRP Software Defined Radio.

Parameters:

• carrier_frequency (float) – Center frequency of the generated signal in Hz.

• sampling_rate – Sampling rate of the generated signal in Hz.

• num_tx_channels (int) – Number of transmit channels to be created. The actual hardware has four by default.

• num_rx_channels (int) – Number of receive channels to be created. The actual hardware has four by default.

• phase_noise (bool) – Whether to model the phase noise of the oscillators. Enabled by default.

• seed (int | None) – Seed with which to initialize the block’s random state.

classmethod Deserialize(process)

Deserialize an object’s state.

Objects cannot be deserialized directly, instead a Factory must be instructed to carry out the deserialization process.

Parameters:

process (DeserializationProcess) – The current stage of the deserialization process. This object is generated by the Factory and provides an interface to deserialization methods supporting multiple backends.

Return type:

X410

Returns:

The deserialized object.

serialize(process)

Serialize this object’s state.

Objects cannot be serialized directly, instead a Factory must be instructed to carry out the serialization process.

Parameters:

process (SerializationProcess) – The current stage of the serialization process. This object is generated by the Factory and provides an interface to serialization methods supporting multiple backends.

Return type:

None
