论文摘要
在这封信中，我们将稀疏的kronecker-rododauct（SKP）编码方案扩展到最初为添加剂白色高斯噪声（AWGN）通道而设计的多个输入多重输出（MIMO）无源随机访问（URA）。通过用于MIMO传输的SKP编码，我们开发了有效的贝叶斯迭代接收器设计，以解决预期的具有挑战性的三线性分解问题。数值结果表明，所提出的设计优于现有的对应物，并且在所有模拟设置中都具有各种天线尺寸和活动用户数量的表现良好。
In this letter, we extend the sparse Kronecker-product (SKP) coding scheme, originally designed for the additive white Gaussian noise (AWGN) channel, to multiple input multiple output (MIMO) unsourced random access (URA). With the SKP coding adopted for MIMO transmission, we develop an efficient Bayesian iterative receiver design to solve the intended challenging trilinear factorization problem. Numerical results show that the proposed design outperforms the existing counterparts, and that it performs well in all simulated settings with various antenna sizes and active-user numbers.
