项目摘要

Astounding spectral efficiencies exceeding 40 bits per second per Hertz have already been achieved in multi-user MIMO systems. Unfortunately, the coordination needed to facilitate transmissions in space, frequency, and time can severely limit efficiency. Moreover, many spectral bands are today deemed unavailable even if no active receiver is nearby and hence resources cannot be used at all.This project fuses three integrated thrusts towards achieving high spectral-spatial efficiency (bits per second per Hertz per square meter) with high spectrum availability (permission to transmit in a particular band at a particular location). First, this project enables a new mode of spectrum availability by exploiting smart primary receivers. The key idea is that a typical primary spectrum transmitter such as a TV broadcaster does not have active receivers in all locations. This thrust realizes an architecture and algorithms for smart primary receivers to inform a controller of their usage, creating vast new dynamically available spatial-spectral resources. Second, this project overcomes fundamental limits in the coordination that is today required for spectrum access. This thrust considers channel sounding and user-state coordination to be a foundational resource of system design that must itself be allocated. An integrated suite of new methods for coordination limited MU-MIMO protocols is developed. The final thrust provides an implementation and measurement study. This thrust yields the first demonstration of spectrum access enhanced by smart primary users and the first multi-user MIMO diverse spectrum system enhanced by coordination limited protocol mechanisms. The platform targets "at scale" experiments via use of maximally amplified signals and real-word scenarios spanning from tower-to-user to indoor WLAN.
在多用户MIMO系统中已经实现了超过40比特每秒每赫兹的惊人频谱效率。不幸的是,促进空间、频率和时间上的传输所需的协调可能严重限制效率。此外,许多频谱带今天被认为是不可用的,即使附近没有活动的接收器,因此资源根本不能使用。该项目融合了三个综合的推力,以实现高频谱空间效率(每秒每赫兹每平方米的比特数)和高频谱可用性(允许在特定位置在特定波段进行传输)。首先,该项目通过利用智能主接收器实现了一种新的频谱可用性模式。 关键的想法是,一个典型的主频谱发射机,如电视广播,并不是在所有位置都有活动的接收机。 这一推动力实现了智能主接收器的架构和算法,以通知控制器它们的使用情况,从而创建大量新的动态可用的空间频谱资源。第二,该项目克服了当今频谱接入所需的协调方面的基本限制。这个推力认为信道探测和用户状态协调是系统设计的基础资源,必须分配。开发了一套用于协调受限MU-MIMO协议的新方法。最后的推力提供了一个实施和测量研究。这一推力产生了第一个演示的频谱接入增强的智能主用户和第一个多用户MIMO多样的频谱系统增强的协调有限的协议机制。该平台的目标是通过使用最大放大的信号和从塔到用户到室内WLAN的真实场景进行“大规模”实验。
