Bases: object

Class for conveniently storing LSPs

Parameters:

• ds (torch.Tensor) – RMS delay spread [s], shape [batch size, num tx, num rx]

• asd (torch.Tensor) – Azimuth angle spread of departure [deg], shape [batch size, num tx, num rx]

• asa (torch.Tensor) – Azimuth angle spread of arrival [deg], shape [batch size, num tx, num rx]

• sf (torch.Tensor) – Shadow fading, shape [batch size, num tx, num rx]

• k_factor (torch.Tensor) – Rician K-factor. Only used for LoS, shape [batch size, num tx, num rx]

• zsa (torch.Tensor) – Zenith angle spread of arrival [deg], shape [batch size, num tx, num rx]

• zsd (torch.Tensor) – Zenith angle spread of departure [deg], shape [batch size, num tx, num rx]

• pathloss (torch.Tensor | None) – Optional path loss [dB] sampled with these LSPs, shape [batch size, num tx, num rx]
