LTE eNodeB PHY Validation

Performance Validation of LTE eNodeB PHY Silicon Solution for a Tier-1 Silicon Manufacturer

Customer Challenges

The customer is a leading Tier-1 semiconductor manufacturer of innovative silicon solutions, which enables intelligent processing in a large variety of products and technologies in the communications domain. The customer wanted to validate the design and processing capabilities of its newly designed LTE eNodeB platform solution. In addition to achieving key performance targets for MIPS, memory and processing cycle's utilization, the customer wanted to prototype and validate the solution for-

  • 3GPP-specifiedperformance conditions with channel impairments on the new platform
  • All signal processing intensive receiver algorithms.

Aricent Solution

Aricent worked closely with the customer to address these challenges. Aricent was quickly able to assemble a team of experienced consultants and engineers, who were able to co-create an optimal cost-effective solution ahead of schedule. Key components of the solution included:

  • Integration of Aricent's LTE eNodeB PHY framework with the customer's target platform
  • Testing for key performance indicators like MIPS, memory and processing cycle's utilization in maximum throughput conditions
  • Demonstration of 3GPP specified performance conditions with channel impairments on the new platform
  • Implementation, optimization and testing of all signal processing intensive receiver algorithms including Channel Estimation, Timing Synchronization Loop, Equalization &Combining, RACH preamble detection and conducting performance benchmarking
  • Testing and validation of the standalone physical layer without the overhead of higher layers
