White Paper: COTS Software Defined Radio for 5G Development

June 20, 2023

26min read time (3500 words)

Commercial-Off-The-Shelf (COTS) Software-Defined-Radio (SDR) products have been traditionally used for Military RADAR and communication applications because of their high performance, and design flexibility. The latest SDR products offer SoC solutions with integrated I/O, ARM processors, and large FPGAs that include intellectual property (IP) for accessing, routing, and processing digital data. Combining these attributes with superior signal integrity, phase-coherent sampling, and multi-channel transceivers a COTS SDR system is an ideal choice for your 5G development platform. This article is designed to familiarize a new user about Software Defined Radio including theory, components and architecture, in a multi-purpose COTS platform that can reduce the time to market their 5G products.

Read this white paper to learn:

  • The history of COTS
  • SDR hardware design and implementation
  • Architecting SDR
  • Theory: Nyquist zone sampling
  • Firmware and IP building blocks for SDR
  • Theory: SNR and digital process gain
  • Software and BSP needs
  • New COTS SDR technology architecture: hardware, firmware, and software
  • Architecture differences for 5G Applications
  • Theory: Cellular phone call
