Zamanla İlintili Kanallarda Güvenli MISO Sistemlerinin Başarımı

Abstract

We consider the problem of secure communication with multiple antenna transmission in temporally correlated channels. In order to achieve a secrecy gain, a channel state information of the intended receiver at the transmitter is required. In this work, we present a limited feedback link by employing differential codebook which utilizes the temporal correlation properties of the wireless channels for a secure multi-antenna system. The secrecy performances are shown for different channel correlations.
