Overview

The MF-TDMA (Multi-Frequency Time Division Multiple Access) Modem IP Core is a high-efficiency, scalable, and standards-compliant solution designed for modern satellite communication and wireless networking systems.

It combines the flexibility of Time Division Multiple Access (TDMA) with the spectrum utilization benefits of multi-frequency operations, enabling dynamic bandwidth allocation and support for multiple users with varying data rate needs.

  • Multi-Frequency Band Support: Operates across multiple carrier frequencies with dynamic channel hopping and flexible frequency reuse patterns.
  • Time Slot Management: Efficient time slot allocation and management with built-in scheduler logic or external interface for real-time MAC control.
  • Integrated PHY Layer: Complete baseband modem including channel coding (e.g., LDPC, Turbo), framing, modulation (QPSK, 8PSK, 16APSK), synchronization, and equalization.
  • Multi-User Access: Enables simultaneous access for hundreds of terminals with independent frequency and time-slot assignments.
  • Adaptive Modulation & Coding (AMC): Supports AMC schemes to optimize spectral efficiency under varying channel conditions.
  • Parameterizable Architecture: Fully configurable FFT size, number of carriers, symbol rate, guard interval, slot duration, and FEC schemes.
  • Burst and Continuous Mode Support: Capable of supporting both burst-mode TDMA and continuous transmission modes based on system requirements.
  • Interoperability: Supports waveform compatibility with existing MF-TDMA-based standards (e.g., DVB-RCS2, proprietary satcom systems).
  • Efficient Spectrum Utilization: MF-TDMA architecture allows for optimal use of available bandwidth, reducing congestion and maximizing channel reuse.
  • Highly Customizable: Easily tailored to fit custom satellite protocols or proprietary tactical communication needs.
  • Enhanced QoS: Ensures reliable communication with dynamic bandwidth provisioning and flexible user prioritization.
  • Low Latency, High Throughput: Pipelined design ensures rapid processing of burst transmissions while maintaining data integrity.
  • Seamless System Integration: Compatible with external MAC controllers, schedulers, and networking stacks via standard interfaces (AXI4, FIFO, AMBA).
  • Global Use Case Ready: Suitable for commercial, defense, emergency response, and remote sensing networks that demand agile and secure connectivity.
  • VSAT Networks
  • Defense Tactical Radios
  • Satellite Terminals
