Abstract:
|
Two polar coding schemes are proposed for the degraded
broadcast channel under different reliability and secrecy
requirements. In these settings, the transmitter wishes to send
multiple messages to a set of legitimate receivers keeping them
masked from a set of eavesdroppers, and individual channels are
assumed to gradually degrade in such a way that each legitimate
receiver has a better channel than any eavesdropper. The layered
decoding structure requires receivers with better channel quality
to reliably decode more messages, while the layered secrecy
structure requires eavesdroppers with worse channel quality to
be kept ignorant of more messages. |
