Open-circuit voltage measurement conjecture. As an alternative to current practice, it would be beneficial merely to measure the open-circuit voltages on the antenna ports.

Array-densification gain conjecture. The gain of array densification should reduce to zero when

Finite-two-dimensional-array conjecture. Although a finite number of transmit antennas is proved optimal for the one-dimensional problem, a finite number of transmit antennas is al…

Discrete-architecture conjecture. The optimal transmit antenna architecture can be realised through a discrete antenna array.

Isolated-position conjecture. The optimal transmit antenna positions are isolated points.

The measurements compare the measured and theoretical free-space path loss for indoor channels at $27.95\,\mathrm{GHz}$, using yagi and patch antennas. A boresight measurement was…

Qualitative two-tone conjecture. The final results and conclusions derived for the Gaussian-signal case should remain qualitatively the same, although the coefficients…

Mainlobe initialization conjecture. A good initial estimate $\hat{x}_0$ should lie within the mainlobe set $\mathcal{B}(x_0)$.

Optimal phase-shift conjecture. The solution $\alpha^*=2\pi/(KT)$ is optimal for other monotonically decreasing pairwise error probability functions.

Let $N_T$ and $N_R$ denote the numbers of transmit and receive antennas in a clustered mmWave MIMO channel, and let the channel rank be the dimension of the channel matrix's range.…
