Broadcasting digital radio, V2X (vehicle-to-vehicle and vehicle-to-infrastructure) and car-radar information is now a reality, and with it comes an increasing number of standards worldwide. We are working to provide software-driven ICs that support multiple global standards using the same system application. 这可能受益于迅速发展的数字电子功能和我们的软件定义无线电(SDR)平台。
RF-CMOS SDR使我们能通过紧耦合的射频前端和基带软件实现多种无线电标准。Traditionally, support was possible for each specific radio standard through expensive hardware implementations. 特定应用的SDR概念不仅具备能够支持多种标准的性能和灵活性,还可提供显著的空间、能源和成本节约。
由于采用一个通用平台架构,因此通过SDR来实施几个面向多个市场的无线电产品已经成为现实,可实现成本和性能的最佳平衡。SDR提供的优势包括低成本拥有tier-1和OEM,加快新标准的上市速度。在对现有基础设施增加新特性时,它还能减少物流支持和运营支出。In addition, SDR ensures easy adaptation to regional variations via software download and over-the-air (OTA) upgrades for quick and cost-effective updates while the radio is still in service.
多标准SDR是无线电和无线连接功能迅速发展的理想驱动器。Our solid RF-CMOS know-how guarantees the combination of maximized flexibility and system integration while ensuring the highest level of performance.
Digital radio broadcast is gaining ground worldwide, with new networks installed, existing ones upgraded and an increasing number of listeners. Compared to AM/FM radio it offers more stations, dramatically improved reception, greater coverage, CD-sound quality without noise, higher bandwidth efficiency for broadcasting and improved mobile reception. It also combines both audio and data services (text, pictures, as well as traffic news, weather, etc.).
数字无线电兴起的一个典型例子是:挪威宣布,2017年将关闭模拟广播,采用数字(DAB)广播。
The spread of digital radio brings diverging requirements to the market, with different digital broadcast standards, each with their own regional footprint. 幸运的是,SDR可以无限灵活地支持广播无线电标准,因而不会限制定制的、特定标准的硬件无线电解决方案。Several terrestrial digital radio standards such as HD Radio, DAB and DRM can be supported with a single multi-standard IC-based platform that can demodulate and process digital terrestrial baseband signals into audio signals and digital data signals.
V2X通信技术为OEM部署作好了准备,为实现无人驾驶汽车铺平了道路。由于有了SDR技术,为汽车制造商和基础设施设备制造商创建一个灵活、高性价比的V2X平台成为可能。
这基于一个采用SDR技术来处理V2X功能的单硬件IC平台。It also handles reception enhancement algorithms from Cohda Wireless, which provide high performance even in more challenging mobility and non-line-of-sight situations. 其结果就是面向V2V和V2I通信的灵活的SDR处理器,支持全球标准,可通过固件下载实现线尾配置。
软件定义无线电方法使OEM能够部署全球V2X平台。
