Irregular Repetition Slotted ALOHA Over Rayleigh Block Fading Channels: Bounds and Threshold Saturation via Spatial Coupling
In irregular repetition slotted ALOHA (IR-SA) systems, a population of devices transmits their packets to an access point (AP) within a frame of slots.The AP decodes Tops these packets by iterative processing between intra- and inter-slot successive interference cancellations.The average normalized offered traffic, as a performance metric, represen
