AI Technical Summary

Technical Problem

Conventional random-access communication methods suffer from inefficient waveform design and inadequate communication reliability due to the need for additional parameters like pilot parts and sparsity, leading to increased complexity and decoding errors.

Method used

A transmitting device uses a low-complexity binary encoder to construct a symbol vector through a Kronecker product of vectors corresponding to sub-constellations, transmitted over a radio frequency signal without a preassigned time slot or frequency, and a receiving device employs a non-coherent equalizer to estimate and decode these vectors without channel state information.

Benefits of technology

This approach enhances communication reliability and channel capacity, supports a larger number of users, reduces decoding errors, and simplifies encoding and decoding processes, even in massive random-access scenarios.
