Abstract
Systems and methods a system for generating Low-Density Parity-Check (LDPC) code for enabling multiple simultaneous users in Asynchronous Scrambled Coded Multiple Access (ASCMA). The system includes transmitter node with source endpoints, each equipped with an encoder unit generating LDPC codeword bits from information bits. An encoder aggregates LDPC codeword bits with replicated information bits to create an aggregated sequence. A modulator unit modulates the sequence into a waveform for transmission over a shared spectrum access channel. The transmitted waveform is asynchronously sent to a receiver node, which includes a gateway linked to destination endpoints. The receiver unit captures a noise-corrupted version of the waveform, and a decoder unit, using soft-input and soft-output techniques, decodes information bits. A Multi-User Interference (MUI) estimator cancels interference levels, allowing the decoder to recover the original information bits associated with the source endpoints.
