A multiple-access channel is considered in which messages from one encoder are confidential. Confidential messages are to be transmitted with perfect secrecy, as measured by equivo...

—We investigate the effects of user cooperation on the secrecy of multiple access channels with generalized feedback (MAC-GF). We show that cooperation can increase the achievabl...
—The capacity region of the finite-state multiple-access channel (FS-MAC) with feedback that may be an arbitrary timeinvariant function of the channel output samples is consider...
The capacity region of the N-sender additive white Gaussian noise (AWGN) multiple access channel (MAC) with feedback is not known in general, despite significant contributions by C...
