Orthogonal reference

1 BS → 1 UE

New experiment:
384-port, 50-symbol coded pilots

Start with a setup

Antenna elements

BS along y BS along z UE along y UE along z

Sounding & frequency grid

Symbols L Subcarriers K

Specify the grid by

B [MHz] Δf [kHz]

B = K Δf. Tones are centered around f_c.

Energy & noise SNR convention Aggregate SNR Γ [dB]

Angles, carrier & element spacing

Local array-frame angles

AoD azimuth [°] AoD elevation [°] AoA azimuth [°] AoA elevation [°]

Arrays lie in yz. Broadside is +x. Azimuth turns from +x toward +y.

Wavelength & aperture Carrier f_c [GHz] Element spacing convention

d / λ d [mm]

One far-field path · balanced orthogonal pilots · known noise variance · unknown complex path gain. Bounds are local and conditional on this model.
