No data-rate gain from full first-hop CSI in distributed orthogonal space-time coding
Full-CSI no-gain conjecture. The data-rate cannot be improved by assuming that the relays have full channel state information of the first hop.

Marginal data-rate improvement from correlated-noise DOSTBCs with channel phase information
Marginal-improvement conjecture. Removing the row-monomial restriction in this correlated-noise, channel-phase-information setting should improve the data-rate only marginally.

The conjectured data-rate bound for DOSTBCs with channel phase information
DOSTBC-CPI data-rate conjecture. The upper bound of the data-rate of a DOSTBC-CPI should be smaller than .
