Abstract
In sporadic machine-to-machine (M2M) communication, for the Code Division Multiple Access (CDMA) system with random access, applying compressed sensing (CS) algorithms to communication processes is a solution of multi-user detection (MUD). Many papers have shown that compressed sensing multi-user detection (CS-MUD) brings the benefits of jointly detecting activity and data. This paper focuses on the benefits of CS-MUD to the design of spread spectrum code in CDMA systems. Simulations show that CS-MUD brings two advantages in the spread spectrum code design: (1) There exist code sets with short code length can accommodate more users. (2) Code sets design is not limited to the design requirements of pseudo-random sequences, and the CS measurement matrix can be used as the code set. That is, CS-MUD provides a new idea for design and selection of spread spectrum code sets.
