Signal Diversity Combining
  • Signal diversity combiner for receiver applications. Combines up to 4 signal replicas
  • Large (256 MB) memory for very large time-diversity
  • Post-detection combining (after demodulation). 4-bit soft-quantized samples from multiple demodulators are re-synchronized to compensate for differential delays and summed coherently to improve signal-to-noise ratio
  • Connectorized 3”x 3” module for ease of prototyping. Standard 40 pin 2mm dual row connectors (left, right). Single 5V supply with reverse voltage and overvoltage protection. Interfaces with 3.3V LVTTL logic
