Advanced MIMO Wireless Communication Equalizer

Interactive Simulation with Complex Channels & Constellation Analysis

Instructions

Follow these steps to explore the equalizer simulation:

  1. Select Modulation Scheme (BPSK, QPSK, 16-QAM, 64-QAM) and MIMO Configuration (Nt × Nr antennas).
  2. Set the SNR (dB) value to simulate different channel conditions.
  3. Click "Simulate Channel" to generate a random MIMO channel matrix.
  4. Observe the signal flow diagram and constellation plots showing transmitted and received signals.
  5. Switch between ZF and MMSE equalizers to compare their performance with the same channel.
  6. Click "Run with New Symbols" to simulate different symbols through the same channel.

Instructions

Follow these steps to analyze performance metrics:

  1. Select Modulation Scheme and Antenna Configuration (Nt × Nr).
  2. Choose a Noise Enhancement Factor to simulate different channel conditions.
  3. Select either ZF or MMSE equalizer technique.
  4. Click "Plot Configuration" to generate a SER vs SNR curve with these settings.
  5. Add multiple curves (up to 5) with different settings to compare performance.
  6. Use "Reset Plots" to clear all curves and start a new comparison.
