In one embodiment, the communication system includes a plurality of transmitters that transmit signals via a random access channel, where each transmitter includes: an encoder that encodes data bits using a two-layer code including an inner medium access control code and and an outer error correcting code; and a modulator that modulates each encoded bit for transmission via the random access channel. In addition, the communication system includes a receiver including: a demodulator configured to demodulate received signals and provide input signals to the decoder; and a decoder configured to iteratively decode data bits received from the plurality of transmitters using message passing between an inner medium access control layer and an outer coding layer to jointly perform contention resolution and decoding."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Coded random access mechanism for communication networks","description":"Coded access communication systems and methods are described.
