LTE UE and eNodeB Design Test Bench

LTE Design Test bench comes with UE, eNodeB and RF combination for aiding the rapid development of eNodeB and UE products by customers. As the unique opportunity Mymo offers accessibility to selective low-level ANSI C-Programs of PHY-MAC-RLC-RRC-PDCP-NAS for UE and eNodeB. Scientists, design engineers and test engineers, working in 3GPP LTE, can have access to low-level C-modules of all layers for modification, enhancement and plug-in of proprietary designed algorithms and measure the performance analysis.

MYMO LTE Design Test Bench

 

MW1000eNB Emulator Benefits:

 

  • Low level C-code access to users across all the layers of eNodeB and UE Design Test-bench. Capture the RF signals either file-based or print-screen based with different debug-level options.

  • Readily available and well-tested eNodeB-UE layers and algorithms with all the features implemented in C. Refer the 3GPP LTE Specifications for physical layer, MAC, Higher Layers features.

  • Rapidly reprogrammable with instant compilation, debugging and running.

  • Multi-core CPU partitioning of desired DL and UL chains for performance optimization

  • Online capture of down-converted IQ signals for offline processing. No separate device needed to capture the IQ waveforms.

  • Time scaling ability for debugging and analysis baseband processing. Example: 30720 samples per ms can be processed at any desired time scale rather than 1ms.

 

The example applications for algorithm and system designs include:

  • Introduction of channel models, interference effects, noise conditions, multipath and fading conditions. The signals can be convoluted with different channel models of users’ choice and can be captured and measured for offline or online processing.

  • Intercarrier interference (ICI) measurements, compensation effects, loss of orthogonality of subcarriers, sampling clock offset effects and estimation and tracking accuracy.

  • CFO estimation and measurements using pilot tones (reference signals) for integer and fractional CFOs.

  • Equalization techniques and their performance differences. Example: ML, MMSE, LS, Sphere, other decision feedback methods.

  • Multi-cell and multi-UE interference impacts and measurements.

  • FEC algorithm design improvements. Example: Tail-biting, Viterbi decoding, Turbo decoding, Rate-matching, Interleaving, scrambling and CRC.

  • SFBC modes of operation and performance analysis.

  • CQI measurements, SNR measurements, Precoding performance.

  • HARQ soft-combining for UL and DL

  • MAC Scheduling, packet multiplexing and de-multiplexing

  • Queuing and scheduling of different traffic data

  • Security and data integrity algorithm design and analysis

  • Logging of different physical, transport and logical channels measurements for message sequencing
