In this paper, the concept of opportunistic bits (OBs) is developed in short-packet communications and investigated from a finite blocklength perspective. OB-based transmission, data unit packet divided into two parts: OBs conventional (CBs). The are not physically transmitted but used to indicate index time slot (TS) when containing CBs transmitted. loading bulk packets multiple TSs can be mod...

We propose and practically demonstrate a joint detection decoding scheme for short-packet wireless communications in scenarios that require to first detect the presence of message before actually it. For this, we extend recently proposed serial Turbo-autoencoder neural network (NN) architecture train it find short messages can be, all “at once”, detected, synchronized, equalized decoded when se...
