On the Capacity of Relaying with Finite Blocklength

In this paper, relaying performance is studied under the finite-blocklength regime. The overall error probability of relaying is derived. Moreover, the authors investigate the blocklength-limited capacity (BL-capacity) of relaying. The authors prove that the BL-capacity of relaying is quasiconcave in the overall error probability. Therefore, the BL-capacity has a global maximum value, which can be achieved by choosing an appropriate error probability. Through numerical investigations, the authors validate our analytical model and compare the performance of relaying under the finite-blocklength regime versus the Shannon capacity regime.
