Query: Optimization of Code Rates in SISOME Wiretap Channels   We propose a new framework for determining the wiretap code rates of
single-input single-output multi-antenna eavesdropper (SISOME) wiretap channels
when the capacity of the eavesdropper's channel is not available at the
transmitter. In our framework we introduce the effective secrecy throughput
(EST) as a new performance metric that explicitly captures the two key features
of wiretap channels, namely, reliability and secrecy. Notably, the EST measures
the average rate of the confidential information transmitted from the
transmitter to the intended receiver without being eavesdropped on. We provide
easy-to-implement methods to determine the wiretap code rates for two
transmission schemes: 1) adaptive transmission scheme in which the capacity of
the main channel is available at the transmitter and 2) fixed-rate transmission
scheme in which the capacity of the main channel is not available at the
transmitter. Such determinations are further extended into an absolute-passive
eavesdropping scenario where even the average signal-to-noise ratio of the
eavesdropper's channel is not available at the transmitter. Notably, our
solutions for the wiretap code rates do not require us to set reliability or
secrecy constraints for the transmission within wiretap channels.
