Massive Machine Type Communication (mMTC) is a major target use case for the sixth generation (6G) communications, which introduces challenges in multiple access schemes. In this dissertation, we introduce a grant-free random access (GFRA) system based on compressed sensing (CS), aiming to simultane...
