Kronecker-Based Non-Orthogonal Sequences of Small Phases for Uplink Grant-Free Access Using the Genetic Algorithm

In massive machine-type communications (mMTC), grant-free access is a key enabler for a massive number of users to be connected to a base station with low signaling overhead and low latency. In this letter, we present a set of Kronecker-based non-orthogonal sequences and study the performance of upl...
