Measurement of Rank and Other Properties of Direct and Scattered Signals

Table 1

Parameters of the measurements.

Name	Number of transmitters	Correlation	PG; Tx 1; dB	PG; Tx 2; dB	SNR; dB
C1S	1	—	0.5	—	41
C2SS	2	Coherent	0.5		45
U2SS	2	Uncorrelated	0.5		40, 32
I2SS	2	Intermediate	High	High	42
C1W	1	—		—	14
C2SW	2	Coherent	0.5		43
U2SW	2	Uncorrelated	0.5		44,

PG is the effective isotropic radiated power dBm.
The DOA was 0° for transmitter 1 (Tx 1) and −15° for transmitter 2 (Tx 2).
The SNR is for one antenna channel (mean value between the channels) and one time sample after IQ, DDC, and calibration and is estimated from data (by the frequency spectrum, not the Capon spectrum). For measurements C2SS, I2SS, and C2SW the stated SNR is for the sum of the two transmitters. The reason for this is that the transmitters could not be separated in the SNR estimation.
