“…Since

| h_{1} |^{2}

and

| g_{1} |^{2}

are assumed to be independent random variables, then Z and Y are also statistically independent. Hence, similar to the steps given for the non‐cooperative spectrum sharing system considered in [35, 36], in the case of a cooperative AF‐relaying spectrum‐sharing system, the CDF of

γ_{sr}

defined in (1), can be obtained from

F_{γ_{sr}} false(γ false) = F_{W} ()(, \frac{γ}{P_{1}}) F_{Z} ()(, \frac{Q_{1}}{P_{1}}) + \int_{Q_{1} / P_{1}}^{+ normal∞} F_{Y} false(γ z false) f_{Z} false(z false) d z,

where

F_{W} false(\cdot false)

is given in (6) and

F_{Y} false(γ z false) = F_{W} false(γ z / Q_{1} false)

. In addition, the expressions for

F_{Z} false(\cdot false)

and

f_{Z} false(\cdot false)

are given in (6) and (7), respectively.…”

“…From the independent non‐identically distributed SUs, by employing a fair user‐scheduling method, explained later, a single SU‐Tx is scheduled to access the spectrum and communicates with the SU‐Rx. As shown in [27], the probability distribution function (PDF) and CDF of the channel's SNR corresponding to the two correlated transmit antennas are expressed by

“…In [25, 26], the performance of an OSTBC‐CRN under antenna correlation is evaluated, where only one single SU is permitted to share the licenced spectrum of a PU. The work in [25] was extended in [27], where identically distributed SUs are taken into consideration for CRN, utilising the opportunistic user‐scheduling. Note that in [25–27], for the sake of simplicity, the interferences from PU to SUs are not considered.…”

“…In distinction with [25–27], this study introduces a far more realistic OSTBC‐CRN system, in which multiple SUs, with independent non‐identically distributed SNRs, have the permission of concurrently using the licenced spectrum of a PU, in which a fair user‐scheduling is employed for giving spectrum access to the SUs. In addition, in this study, a more practical system model is considered, in which the interfering signals from SUs to PU as well as the interferences from PU to SUs are taken into consideration.…”
