  abstract={The adaptation of communication systems to the current channel state is
a crucial step towards higher spectral efficiencies and more robust
systems. Obviously, the whole system has to be considered in the system
optimization, which includes the applied channel coding. This, however,
has been neglected in older works and only recently gained some
attention. We propose an efficient extension to the original approach
of Krongold et al., which uses the bisection method to solve the
resulting convex optimization problem. The simulated AWGN performance
of a set of code and modulation combinations (modes) will be used to
describe the required signal-to-noise-ratio (SNR) for a specific
subcarrier rate. Adaptation of the code rate additionally allows for
higher flexibility in comparison to fixed code rate scenarios.
