Overview

The OFDM Modem IP Core is a high-performance solution for wireless and broadband systems like 5G, Wi-Fi, LTE, satellite, and tactical radios. It offers full PHY baseband functionality with support for adaptive modulation, channel estimation, and configurable IFFT/FFT sizes. Optimized for low-latency and robust performance, it’s ideal for both fixed and mobile applications.

  • Complete Baseband Processing: Includes IFFT/FFT engine, cyclic prefix insertion/removal, windowing, pilot insertion, channel estimation, equalization, and symbol mapping/de-mapping.
  • Configurable Parameters: Supports dynamic FFT sizes (64, 128, 256, 512, 1024, 2048), cyclic prefix lengths, modulation schemes, and guard intervals.
  • Modulation Support: QPSK, 16-QAM, 64-QAM, 256-QAM, adaptable based on channel conditions or system requirements.
  • Pilot and Preamble Support: Embedded pilot symbols and preamble structures for synchronization, frequency offset correction, and channel estimation.
  • MIMO Compatibility: Designed to integrate with 2x2, 4x4, and higher MIMO architectures for enhanced throughput and diversity gains.
  • Adaptive Modulation and Coding (AMC): Enables real-time modulation adjustment per subcarrier, improving efficiency and throughput under varying SNR conditions.
  • Easy Integration with MAC and RF: Standard interfaces (AXI4-Stream, FIFO, custom) for seamless connectivity with MAC layer and RF front ends.
  • High Throughput, Low Latency: Designed for speed-critical applications, delivering real-time symbol processing for gigabit-class systems.
  • Robust in Multipath Environments: OFDM structure inherently resists ISI and provides better performance in fading channels—ideal for mobile and urban deployments.
  • Flexible Deployment Options: Scalable architecture supports diverse deployment needs—from narrowband tactical radios to ultra-wideband 5G and Wi-Fi systems.
  • Customizable and Extensible: Easy to tailor for proprietary waveform designs, unique carrier spacings, or non-standard preambles and training sequences.
  • Global Standards Compatibility: Complies with and adapts to leading wireless standards: 802.11a/g/n/ac/ax, LTE, DVB-T/H, 5G NR, WiMAX, and more.
  • FPGA and ASIC Ready: Optimized for resource-efficient FPGA implementations and performance-focused ASIC designs.
