Abstract
Tomlinson-Harashima precoding (THP) can be used in degraded Gaussian broadcast channels in order to exploit the broadcast gain with low required complexity at the receivers. In this work we derive the achievable rates for this technique with QAM constellations as signaling alphabets. We compare the performance of THP with superposition modulation.
