论文摘要
用户对增加无线容量的需求继续超过供应，因此为了满足这种需求，新的MIMO无线物理层技术已经取得了重大进展。现在，高性能系统仍然不切实际，仅仅是因为它们的算法在计算上的要求极高。为了获得最佳性能，经常需要以用户数量和每个用户的数据速率以指数率提高的计算数量。因此，基站的计算能力正成为无线容量的关键限制因素之一。 Quamax是第一个大型MIMO集中式无线电网络设计，通过利用量子性退火来解决此问题。我们已经在2,031个Qubit D-Wave 2000Q Quantum Neelealer上实施了Quamax，该领域的最先进。我们的实验结果评估了对真实和合成MIMO频道痕迹的实施，表明在2000Q上的10〜 $ $ $ $ s的计算时间可以启用48个用户，48个AP ATENNA BPSK在20 dB SNR上以20 dB SNR的通信，其一点误差率为$ 10^{ - 6} $ $ 10^{ - 6} $和1,500 BICTE帧错误率，$ 10^^$ 10^^^$ 10^^ - 4}。
User demand for increasing amounts of wireless capacity continues to outpace supply, and so to meet this demand, significant progress has been made in new MIMO wireless physical layer techniques. Higher-performance systems now remain impractical largely only because their algorithms are extremely computationally demanding. For optimal performance, an amount of computation that increases at an exponential rate both with the number of users and with the data rate of each user is often required. The base station's computational capacity is thus becoming one of the key limiting factors on wireless capacity. QuAMax is the first large MIMO centralized radio access network design to address this issue by leveraging quantum annealing on the problem. We have implemented QuAMax on the 2,031 qubit D-Wave 2000Q quantum annealer, the state-of-the-art in the field. Our experimental results evaluate that implementation on real and synthetic MIMO channel traces, showing that 10~$μ$s of compute time on the 2000Q can enable 48 user, 48 AP antenna BPSK communication at 20 dB SNR with a bit error rate of $10^{-6}$ and a 1,500 byte frame error rate of $10^{-4}$.
