Overview

The Doppler Channel IP is a Doppler shift frequency (DSF) generator capable of introduce a shift frequency to samples as a phase offset. The IP was developed with the aim of allowing the performance evaluation of a low earth orbit (LEO) digital communication system. Unlike a software-based DSF generator, which might take several hours and even days for the stated purpose, a hardware-based DSF generator requires significantly less time. Run-time is reduced by several orders of magnitude.

Key features

  • Support for orbital heights (h) in the range from 200 to 2000 km
  • Support for carrier frequencies ( fc) in the range from 137 to 2200 MHz
  • Support for sample frequencies ( fs) in the range from 500 Ksps to 500 Gsps
  • Support variations in the initial elevation angle due to different latitudes, obstructions in the visibility region, and regulatory requirements
  •  Performance Figures
    • Symbol rate of 0.62 Gsmpl/s at 620 MHz.
    • Latency of 78.98 ns at 620 MHz.

Benefits

  • Design-time configuration of the LEO altitudes range.  Besides, the number of angles in the range from 0 to  rad, followed by the pre-calculation of sine and cosine  functions. The IP uses the fast inverse square root algorithm, set up with three iterations to ensure accuracy.
  •   Low-power and low-complexity design.
  •   AXI4-Stream interface for easy integration.
  •   Available for ASIC and FPGAs (AMD Xilinx, Intel).

Applications

  • LEO Digital communication systems for which a Doppler channel is required

 

What’s Included?

  • VHDL source code or synthesized netlist with testbench
  • HDL and Bit-accurate Matlab, C or C++ simulation models
  • C++ firmware (Yocto/Petalinux compatible)

Three Major Inflection Points for Sourcing Bluetooth Intellectual Property

Synopsys is now shipping support for Bluetooth® 5.4, the latest specification from the Bluetooth SIG (Special Interest Group). The enhancements in Bluetooth 5.4 will open additional markets and use cases. This is one of the many inflection points in the Bluetooth Low Energy market that will be discussed in this paper.

Part 2: Opening the 5G Radio Interface

Carriers are now deploying 5G across the globe driven by the need to keep up with relentless mobile data growth. 5G New Radio (NR) operates at higher frequencies to increase bandwidth, but at the expense of range. There will therefore be a need for a much larger number of 5G RUs to provide the same coverage. The availability of cost-effective, reliable and open 5G radio units is therefore critical.

An Integrated, Tunable RF Filter: an Enabler for Reconfigurable Front-Ends

This paper presents the design and performance of a key RF circuit necessary for the realization of a reconfigurable, integrated RF front-end: a tunable frequency, selectable bandwidth, on-chip, “SAW replacement” filter. The on-die tunable filter presented here has a tunable center frequency up to 1 GHz, a selectable bandwidth up to 40 MHz, and an adjacent channel rejection down to 60 dB.

Design considerations for integrated CMOS receivers

To meet the demands for the multi-band, multi-mode wireless standards in the current market, a highly integrated wireless receiver (RX) is desired. CMOS technology has become the technology of choice for the integrated receiver design.

Silicon IP for Programmable Baseband Processing

An efficient IP reuse strategy relies on IP blocks with wide applicability. That makes generic blocks, such as programmable processors preferable. However, in many applications such as handheld wireless terminals, additional silicon area and power consumption compared to fixed function solutions can not be accepted.
