Since 0/1 space hopping technique in forward training mode has security problems after the leak of space hopping pattern, a backward training technique with weight-feedback is proposed. Through backward training between transmitter and target user, the target user can obtain weights that are equivalent with those generated from forward training, while eavesdropper, even if she steals the space hopping...
0/1 space hopping technique is a multi-antenna secure wireless transmission scheme which exploits the space spectrum at both the transmitter side and the receiver side. However, 0/1 space hopping using the forward training method (FTM) may lead to interception when the training method and the space hopping pattern are both known to an eavesdropper. The backward training method with weight-feedback...
