Advanced MIMO Wireless Communication Equalizer

Interactive Simulation with Complex Channels & Constellation Analysis

Instructions
  1. Getting Started: This simulation demonstrates MIMO equalization techniques (ZF and MMSE) for wireless systems.
  2. Configure Setup: Select your modulation scheme (BPSK, QPSK, QAM) and MIMO configuration (Nt transmit × Nr receive antennas).
  3. Set Parameters: Adjust the SNR value to simulate different channel conditions.
  4. Simulate Channel: Click the "Simulate Channel" button to generate a random MIMO channel and observe equalization.
  5. Compare Equalizers: Switch between ZF and MMSE equalizer types to compare their performance.
  6. Analyze Results: Examine the signal flow diagrams, constellation plots, and performance metrics.
  7. Run New Simulation: Click "Run with New Symbols" to repeat with different random symbols while keeping the same channel.

Instructions
  1. Performance Analysis: This tab allows you to compare SER (Symbol Error Rate) for different configurations.
  2. Select Parameters: Choose modulation scheme, antenna configuration, and noise enhancement factor.
  3. Choose Equalizer: Select either ZF or MMSE equalization technique.
  4. Generate Curve: Click "Plot Configuration" to add a SER curve to the chart.
  5. Compare Results: Add up to 5 different configurations to compare their performance.
  6. Start Over: Click "Reset Plots" to clear all curves and begin a new comparison.
  7. Interpretation: Lower curves indicate better performance. MMSE typically outperforms ZF at low SNR values.
