Enhancing CRDSA with Transmit Power Diversity for Machine-Type Communication

Alvi, Sheeraz; Durrani, Salman; Zhou, Xiangyun


Contention resolution diversity slotted ALOHA (CRDSA) is a promising solution to meet the challenge of designing efficient random access in future wireless networks. In this work, we consider CRDSA with transmit power diversity where each packet copy from a device is transmitted at a randomly selected power level. This results in inter-slot received power diversity, which is exploited by employing a signal-to-interference-plus-noise ratio based successive interference cancellation (SIC)...[Show more]
