... a same way, the knowledge of a TNAR allows to increase the performance in comparison with an absence of TNAR. Finally, for a given set of total noise parameters, the a priori knowledge of the ... data When the matrices R and C are estimated from both the K primary and the K’ secondary data, and assuming that the samples bTv(nT)’ (0 ≤ n ≤ K’ − 1) also verify assumptions A1 , A2 and ... noncircular total noise. From expression (10 ) and assumptions A1 and A2 , using the fact that a n = a n* and taking the logarithm of (9), it is easy to verify that a sufficient statistic for the...
