Capabilities

Digital Signal Processing

Peralex specialises in delivering custom-tailored digital signal processing (DSP) software with high standards for performance and stability. We partner closely with universities and industry leaders to ensure that our cutting-edge signal processing solutions always track the latest technology trends and advances.

Our custom DSP pipelines leverage the latest hardware acceleration technologies and frameworks to meet the most demanding bandwidth requirements. Peralex also excels in designing distributed and networked radio surveillance systems with tight synchronisation requirements.

Signal Intelligence

Peralex boasts a rich history of providing sophisticated SIGINT hardware and software solutions that can meet the stringent performance and reliability standards of our clients. These solutions span a broad spectrum of applications in communications intelligence (COMINT) and electronic defence (ED/EW).

Applications in which we have proven our SIGINT capabilities include:

Classical and super-resolution radio direction finders (DF)
Distributed time difference of arrival (TDOA) systems
Radar data acquisition hardware
High-sensitivity, high-bandwidth electronic intelligence receivers
Advanced radar pulse analysis, classification, and deinterleaving algorithms
Target tracking algorithms across diverse state spaces
Automatic radio signal detection and classification
Radio signal modulation identification and decoding
UAV signal classification
Frequency hopping radio detection and tracking

Machine Learning and AI

Peralex has developed custom machine learning models and pipelines for a range of applications in the signal processing, SIGINT, radar, and geospatial domains. We take a hands-on approach of working with customers to analyse their datasets and identify key features in order to select the most appropriate data representations and model architectures.

After training, transfer learning, or fine-tuning, these models can be deployed in both edge and cloud environments using the framework and runtime environment best-suited to the customer.

Hardware Acceleration

Most DSP solutions developed by Peralex leverage one or more forms of hardware acceleration in order to meet the continuously evolving bandwidth and timing requirements of our industry partners. Our engineers are equipped with the technology and knowledge to aid clients in accelerating their CPU-bound workloads using GPUs, FPGAs, and DSPs.

Peralex has designed effective CUDA and FPGA-accelerated pipelines for applications including signal geolocation systems (direction finders and TDOA/DDOA), active and passive radars, AI signal classifiers, and signal intelligence systems (SIGINT, ELINT and COMINT).

Embedded Systems and IoT

Peralex has designed and developed a number of IoT solutions with a focus on power-efficient embedded systems. These distributed solutions are highly industrialised, secure, and fault-tolerant. In-depth knowledge of power-efficient networking technologies like LoRa and BLE allows us to design battery powered devices with long service lives, ideal for agriculture or infrastructure monitoring.

We take a holistic approach to embedded product development, providing customers with invaluable advice on topics ranging from hardware and firmware design to security, scalability, and deployment strategies.
