Two-way discriminatory channel estimation for non-reciprocal wireless MIMO channels
The idea of discriminatory channel estimation (DCE) was recently proposed to differentiate the performance at a legitimate receiver (LR) and an unauthorized receiver (UR) by carefully designing the training phase of transmission. In particular, an artificial noise (AN) signal is inserted into the training signal to degrade the channel estimation performance at UR. However, without careful design, the inserted AN may potentially leak into LR's channel causing degradation in LR's performance. In...[Show more]
