Abstract—The paper presents design of a linear precoder
for orthogonal space-time block coded orthogonal frequency
division multiplexing (OFDM)-based multiple-input multipleoutput
(MIMO) antenna cognitive radio (CR) when operating
in correlated Rayleigh fading channels. Unlike previous studies
on precoder design for CR, this proposed linear precoder is
capable of handling both transmit and receive correlation in a
multi-carrier based CR system. The linear precoder is designed
to minimize an upper bound on the average pairwise error
probability, constrained to a set of per subcarrier transmit power
constraints at the CR transmitter and a set of interference power
thresholds at primary user receivers. The CR transmitter exploits
the knowledge of transmit and receive correlation matrices while
designing the precoder. It is shown that the linear precoder design
problem is convex with these constraints, and convex optimization
techniques are exploited to derive an efficient algorithm to
obtain the optimal precoder matrices. Computer simulations are
performed to investigate the performance of the proposed linear
precoder in a CR system.

It got past the reviewers & editor, so maybe it is true & possible. Perhaps best to read the paper & if it is not clear maybe consult the authors A. Punchihewa, Vijay K. Bhargava,Charles Despins ?
