Signal Processing

Collect – Analyze – React

From careful filtering of analog sensor lines to sophisticated digital signal processing, Cardinal Peak helps teams use signal processing to achieve the highest level of performance. For example, voice enablement has introduced a variety of audio signal processing challenges, including wake-word recognition, echo cancellation, and acoustic beam forming. Cardinal Peak’s deep experience with giving devices a voice of their own has helped our customers launch products with both OK Google and Alexa wake-words. As an Alexa Voice Services partner and with broad audio expertise, we help select and implement both hardware and IP solutions to meet performance, schedule and budget requirements for our clients.

When it comes to connectivity, Cardinal Peak has devoted years to implementing familiar standards like LTE, Bluetooth, Zigbee, and Wi-Fi as well as less familiar standards like Ultra-Wideband and LoRa. For truly unique wireless applications, Cardinal Peak has helped customers design, model and implement proprietary waveforms built atop software-defined radios. We routinely help with hardware, embedded software, custom antennas, regulatory certification and end-to-end testing.

Cardinal Peak’s DSP architects are ready to support any stage of development, from preliminary block diagrams, to high level modeling in tools like Matlab and Python, to implementing algorithms in constrained environments, including FPGAs, dedicated DSPs, and general purpose processors.
