Overview

The High Data Rate (HDR) Receiver Modem is a high-performance solution for reliable, real-time data reception in satellite, aerospace, defense, and high-speed terrestrial systems. Supporting various modulation and coding schemes, it ensures uninterrupted, high-throughput operation over RF, optical, or cable links. FPGA/ASIC-ready, it’s optimized for integration, precision, and performance in challenging signal environments.

  • Ultra-High Data Rates: Supports reception bandwidths ranging from hundreds of Mbps to several Gbps depending on modulation and hardware configuration.
  • Advanced Demodulation Techniques: Supports QPSK, 8PSK, 16QAM, 64QAM, and custom higher-order modulation schemes for bandwidth efficiency and signal robustness.
  • Soft Decision Decoding: Integrated with soft-decision Viterbi/LDPC/BCH decoders for high error correction accuracy and improved BER performance.
  • Automatic Gain Control (AGC): Real-time AGC loop to adaptively manage signal amplitude variation across noisy channels.
  • Carrier and Symbol Synchronization: Robust timing and carrier recovery modules for stable operation under frequency offset and phase noise conditions.
  • Flexible Coding Support: Compatible with convolutional codes, Turbo codes, LDPC, and BCH for customizable FEC configurations.
  • High Dynamic Range ADC Interface: Easily interfaces with high-resolution ADCs for wideband signal capture.
  • Built-in Diagnostics: Real-time monitoring of Signal-to-Noise Ratio (SNR), Bit Error Rate (BER), constellation diagrams, and link status.
  • Simulation-Tested, Lab-Proven: Fully verified under realistic channel models including AWGN, Rayleigh, and Rician fading.
  • Reliable High-Speed Reception: Optimized for streaming and burst data reception even in spectrally dense environments.
  • Versatile Application Fit: Works across multiple domains including satellite downlinks, remote sensing, tactical communications, and industrial data capture.
  • Customizable Modem Architecture: Modular design allows adaptation to specific link budgets, spectrum allocations, and compliance requirements.
  • Low-Latency, Real-Time Performance: Critical for mission-sensitive data acquisition where speed and reliability are paramount.
  • Secure and Scalable: Can be integrated with custom encryption/decryption blocks to ensure data confidentiality in defense and critical infrastructure use cases.
