Software Stack for 4G/LTE User Equipment (UE)

Orthogone is recognized as a leader in embedded software design. Needless to say that our software engineering team likes challenges. For this project, Orthogone was involved in the architecture, design, integration, and optimization of a 4G LTE/LTE-A User Equipment (UE) System-on-a-Chip (SoC). We have also participated in several field trials and demonstrations that led to a successful company acquisition by a large semiconductor company.

Our software engineering team implemented several algorithms to improve throughput and power consumption performances. This project was a clear example of how Orthogone’s team excels at optimizing software performances even when working with limited resources. The throughput of the 4G LTE/LTE-A UE was optimized by a factor of eighty after our team re-architected and re-designed the traffic flow and the buffer management between the different embedded processors of the SoC. The project was a success despite the very aggressive project schedules.

A few examples of key modules implemented by Orthogone are:

  • FFT Processor
  • Buffer Management
  • MIMO Decoder
  • FEC Decoder, CRC Checker
  • Channel Estimation
  • Soft Demapper
  • HARQ


“We had an acute requirement in our network monitoring systems department for a senior engineer and Orthogone came highly recommended.

Orthogone integrated seamlessly with our team and brought a level of professionalism and expertise that quickly earned the respect and confidence of our engineers.

Our experience working with Orthogone was and continues to be a great one.”
