Avaliant LDPC Validation Service
Avaliant presents a high-throughput, flexible, and cost-effective LDPC Validation service. The service allows the user to measure the performance of an LDPC code at astonishingly low error rate. LDPC Validator has quick turnaround time because it was designed to seamlessly take advantage of a massively parallel General Purpose Graphics Processor (GPU) architecture. The LDPC Validation service currently supports the following parameters:
- LDPC Code Structure: H parity matrix (regular, irregular, punctured, shortened, varying block size) and G matrix
- LDPC Decoder Parameters: number of iterations, exact or approximate Log-Likelihood Ratio (LLR)
- Modulation (DOCSIS 3.1): BPSK, QPSK, 8QAM, 16QAM, 32QAM, 64QAM
The Avaliant LDPC validation service outputs bit error rate, block error rate, and average iterations per signal-to-noise ratio (SNR). The service has been validated using known LDPC standards including 802.11ad, 802.16, and DVB-S2. The Avaliant LDPC Validation tool has been used by a large aerospace company.
