Slow fading broadcast channels can model a wide range of applications in\nwireless networks. Due to delay requirements and the unavailability of the\nchannel state information at the transmitter (CSIT), these channels for many\napplications are non-ergodic. The appropriate measure for designing signals in\nnon-ergodic channels is the outage probability. In this paper, we provide a\nmethod to optimize STBCs based on the outage probability at moderate SNRs.\nMultilevel polar coded-modulation is a new class of coded-modulation techniques\nthat benefits from low complexity decoders and simple rate matching. In this\npaper, we derive the outage optimality condition for multistage decoding and\npropose a rule for determining component code rates. We also derive an upper\nbound on the outage probability of STBCs for designing the\nset-partitioning-based labelling. Finally, due to the optimality of the\noutage-minimized STBCs for long codes, we introduce a novel method for the\njoint optimization of short-to-moderate length polar codes and STBCs.\n
