aeris-channel

3GPP stochastic channel modeling for 5G NR and 6G research, development, and hardware-in-the-loop workflows.

aeris-channel implements channel-modeling capabilities including:

• 3GPP TR 38.901 CDL, TDL, and stochastic channels.
• TR 36.777 aerial-UE/UAV channels.
• TR 38.811/38.821 non-terrestrial-network channels.
• MIMO, massive-MIMO, XL-MIMO, and near-field extensions.
• ISAC and channel-estimation utilities.
• Time-domain, frequency-domain, resource-grid, and impulse-response export interfaces.

Installation

Install the released package:

pip install aeris-channel

The package installs aeris-license>=1.0.2,<2.0 automatically.

Supported platforms are Windows and Linux with CPython 3.11, 3.12, 3.13, and 3.14.

License requirement

A valid aeris.lic is required at runtime. Obtain licensing through the approved Keysight process, configure the license location according to the provided licensing instructions, then import the package.

Quick start

from aeris_channel.tr38901 import (
    StochasticChannelConfig,
    generate_stochastic_channel,
)

config = StochasticChannelConfig(
    scenario="UMi",
    carrier_freq_hz=3.5e9,
    n_tx=2,
    n_rx=2,
    num_time_samples=64,
    seed=42,
)
result = generate_stochastic_channel(config)

print(result.H.shape)  # (2, 2, 64)
print(result.pathloss_db)

Documentation and examples

The version-matched public documentation and examples bundle describe installation, channel configuration, and runnable workflows. Use assets marked as compatible with the installed package version.

Examples cover:

• Basic CDL, TDL, and stochastic channels.
• TR 38.901 spatial consistency and custom profiles.
• NTN and aerial-UE channels.
• Beam management, massive MIMO, and XL-MIMO.
• ISAC sensing.
• System-level resource grids, link-level time-domain application, RF/HIL streaming, and PROPSIM impulse-response export.
