In this work, we analyze a probabilistic shaping based dirty paper coding (DPC) scheme on a two user multiple input single output (MISO) broadcast channel (BC) and evaluate rate region of the users in the finite block length regime by utilizing analytic approximations introduced for shaping and channel coding parts of DPC. The DPC scheme can be implemented with low complexity and enlarges rate region of the users in finite block length regime substantially compared to linear precoding and time sharing strategies.
