Overview

DVBS2_DEMOD.vhd performs the demodulation based on three tracking loops: carrier tracking (for coherent demodulation), symbol timing tracking, and AGC. Each output bit’s quality is expressed as Log-Likelihood Ratio (LLR) for use. The receiver operates in two clock domains: global clock CLKRXg (half the ADC sampling rate) is mostly for demodulation.

Key features

  • Inputs: two DDR complex (I,Q) baseband samples, 16-bit precision. ADC sampling rate is twice the clock frequency fCLK RXg
  • Maximum payload bit rate: > 675 Mbits/s (8-PSK, rate 9/10, Xilinx Ultrascale+ -2)
  • Modulation type: Automatic detection on a frame-to-frame basis: QPSK, 8-PSK, 16APSK, 32APSK
  • Maximum modulation symbol rate (ultrascale+ -2 speed grade): > 250 MS/s
  • Output:
    • Single or multiple MPEG Transport Stream. 188-Byte fixed length frames, Bytewide.
    • Single or multiple Generic Stream (packetized or continuous). Byte-wide.

Benefits

  • Flexible programmable features:
  • Modulation symbol rate, frequency offset, SRRC filter roll-off.
  • Output type: BBFRAME or stream (transport stream, generic stream packetized, generic bit stream)

What’s Included?

  • VHDL source code
  • GNU radio project and Matlab conversion .m program for generating DVB-S2 waveforms.
  • VHDL testbench
  • PRBS11 test sequence generator, AWGN noise generator

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.
