论文摘要
毫米波（MMWave）和Terahertz（THZ）频率的宽带带宽刺激了无线传感，成像，位置，位置，云计算等的各种应用。这些新兴应用程序激发了无线通信硬件，以多吉赫兹（GHZ）带宽以标称成本，尺寸最小和功耗。当前用于研究和测量无线通道的通道探测系统实现利用了来自多个制造商的众多市售组件，这些组件可导致组成部分之间具有许多昂贵且脆弱的电缆互连，并且通常在一个GHz下实现系统带宽。本文提出了一个评估板（EVB）设计，该设计具有基于滑动相关器的通道音响器，并在65 nm CMOS技术中制造的单个整体集成电路（IC）中，具有2 GHz无效的RF带宽。 EVB景观为信号接口，放大，缓冲提供了必要的外围设备，并使其能够集成到通道发声系统的发射器和接收器中，从而通过集成设计降低了复杂性，大小和成本。 EVB上的频道声音IC是世界上首先使用低成本CMOS技术报告每秒千兆子带操作，从而使全球研究社区现在具有廉价且紧凑的通道声音系统，具有纳米秒时间分辨率能力，可在无线通道中检测多径信号。
Wide swaths of bandwidth at millimeter-wave (mmWave) and Terahertz (THz) frequencies stimulate diverse applications in wireless sensing, imaging, position location, cloud computing, and much more. These emerging applications motivate wireless communications hardware to operate with multi Gigahertz (GHz) bandwidth, at nominal costs, minimal size, and power consumption. Channel sounding system implementations currently used to study and measure wireless channels utilize numerous commercially available components from multiple manufacturers that result in a complex and large assembly with many costly and fragile cable interconnections between the constituents and commonly achieve a system bandwidth under one GHz. This paper presents an evaluation board (EVB) design that features a sliding correlator-based channel sounder with 2 GHz null-to-null RF bandwidth in a single monolithic integrated circuit (IC) fabricated in 65 nm CMOS technology. The EVB landscape provides necessary peripherals for signal interfacing, amplification, buffering, and enables integration into both the transmitter and receiver of a channel sounding system, thereby reducing complexity, size, and cost through integrated design. The channel sounder IC on the EVB is the worlds first to report gigabit-per-second baseband operation using low-cost CMOS technology, allowing the global research community to now have an inexpensive and compact channel sounder system with nanosecond time resolution capability for the detection of multipath signals in a wireless channel.
