    Per Vices Corp. has launched an upgraded version of its high-performance software-defined radio (SDR) platform Cyan EC (extended channel).

    Cyan EC enables up to 64 digital signal processing (DSP) channels across 16 physical SMA ports. This extension allows Cyan EC users to break up the one large bandwidth physical chain into multiple digital channels, allowing the radio platform to do the multiplexing.

    By providing additional digital chains, which are coherently superimposed into a single physical channel, the computational complexity required to address wide bandwidths is further reduced, and allows for processing over multiple cores on a single host system or across multiple host systems concurrently.

    “We are excited that customers have already used and integrated our platform into their products,” said Victor Wollesen, CEO of Per Vices Corp “The additional processing capability provided by this option allows our customers to improve performance and implement more advanced applications using existing computational resources. I believe Cyan EC is the highest channel count software-defined radio commercially available.”

    The Cyan EC product option enables engineers and system integrators to realize the benefits of both the high-bandwidth SDR and having more independent channels to ease the complexity associated with processing the high amount of data by breaking it up into separate channels. This further helps to achieve better spurious-free dynamic range (SFDR), sensitivity and signal-to-noise ratio (SNR) while continuing to offer a high throughput SDR solution.

    Cyan EC benefits engineers and integrators across different markets including GNSS/GPS, radar systems, magnetic resonance imaging (MRI) receivers and exciters, and spectrum monitoring, as well as test and measurement.

    Per Vices Corp. has been named one of the Top Defence Companies in Canada for 2021 by Canadian Defence Review, a defense and military magazine. A new inclusion to the list for 2021, Per Vices specializes in software-defined radio (SDR) solutions that are integrated into radar, GNSS/GPS, satellite, aerospace and communications systems.

    The company is growing and expanding its operations and product line to satisfy the stringent and advanced requirements of its clients and their applications.

    “We are incredibly honoured to be added to this list,” said Brandon Malatest, COO, Per Vices Corp. “This shows recognition and support for high performance manufacturers and companies that are bringing innovative solutions to the table, both within Canada and internationally. We offer the best software defined radio solutions commercially available and work closely with our customers to solve challenges for mission critical applications.”

    The 100 companies, which must have manufacturing, R&D or service operations in Canada, are evaluated by Canadian Defence Review editorial staff and independent advisors. They are ranked on factors such as economic impact to the country, research and development initiatives, innovation, contribution to the nation’s security, and contract wins. The list is used to showcase Canadian technological innovation and its defence industry.

  • Software-based GNSS receiver available on Cadence digital signal processor

    A software-based GNSS receiver from Galileo Satellite Navigation (GSN) is now available for the Cadence Tensilica Fusion F1 digital signal processor (DSP).

    The software-based GNSS receiver allows customers to add full GPS functionality with design flexibility and long-term upgradeability at a minimal cost, low power and no physical size to today’s cost-sensitive internet of things (IoT) applications, according to Cadence Design Systems.

    To get the lowest possible power, GSN accelerated the performance of its GPS software receiver by creating several custom instructions to run on the Tensilica Fusion F1 DSP. As a result, the GPS software requires less than 110 MHz for full 12-satellite functionality.

    Additionally, with this software-based solution, customers can reduce the overall processor requirements to meet less-demanding location-based use cases such as asset tracking.

    “The Tensilica Fusion F1 DSP delivers outstanding performance for the implementation of our GNSS receivers, providing a low-power footprint required for IoT applications,” said Eli Ariel, CEO at GSN. “This enables customers to easily upgrade their Fusion F1 DSP-based designs to future satellite systems such as Beidou, GLONASS and Galileo via software. By leveraging several customized instructions in the Fusion F1 DSP, we were able to keep the required processor speed at the same frequency compared to DSPs with more than three times the processing power.”

    “GSN’s software-based approach for GNSS allows our Fusion F1 DSP customers to precisely scale their GNSS receiver requirements to meet their applications needs,” said Gerard Andrews, group director marketing, at Cadence. “The availability of GSN’s technology on this low-power DSP platform allows our customers to add location-based services at minimal cost and power.”

    The Tensilica Fusion F1 DSP offers low-energy, high-performance control and signal processing for a broad segment of IoT/wearable markets. This highly configurable architecture is specifically designed to excel at always-on processing that requires a merged controller plus DSP, ultra-low energy and a small footprint.

    The DSP is efficient in running the narrowband wireless communications standards typically associated with IoT device communications, including protocols such as Bluetooth Low Energy, Thread and Zigbee using IEEE 802.15.4, Wi-Fi 802.11n and 802.11ah and GNSS.
