A Bit-Mapping Strategy for Joint Iterative Channel Estimation and Turbo-Decoding
Abstract— In this paper, we investigate Turbo-coded transmission over a temporally correlated flat Rayleigh fading channel. Conventionally, channel estimation is performed prior...

Assessing discreet packet-dropping attacks using nearest-neighbor and path-vector attribution
— A Mobile Ad-Hoc Network (MANET) is considered with nodes that may act selfishly or maliciously by simply dropping data packets rather than forwarding them. We study a distribu...
