Random Access Protocols With Collision Resolution in a Noncoherent Setting

Year: 2015

Type: article

Abstract: Wireless systems are increasingly used for machine-type communication (MTC), where the users sporadically send very short messages. In such a setting, the overhead imposed by channel estimation is substantial, thereby demanding noncoherent communication. In this letter, we consider a noncoherent setup in which users randomly access the medium to send very short messages to a common receiver. We propose a transmission scheme based on Gabor frames, where each user has a dedicated codebook of M possible codewords, while the codebook simultaneously serves as an ID for the user. The scheme is used as a basis for a simple protocol for collision resolution.
