The antenna-scaling conjecture for full-duplex MIMO precoding
Let a full-duplex multiuser MISO system use MIMO precoding with an increasing number of access-point transmit and receive antennas, and let the downlink signal-to-interference-plus…

Conjecture on the optimal number of SVD-MIMO streams
For a point-to-point SVD-MIMO downlink system, let $m$ denote the number of transmitted streams, let $\rho$ be the transmit signal-to-noise ratio, and let $\beta$ denote the releva…

Conjecture that the SD-FEC limit paradigm underestimates spectral efficiency for 2048QAM
SD-FEC limit conjecture. The use of the SD-FEC limit paradigm in the reported record results, where a pre-FEC BER threshold obtained for $4$ QAM was used for $2048$ QAM, is incorrect…
