AWGN Channel

Basic channel model, thermal noise scaling with bandwidth

Real-World Applications

Deep space communications (like Mars rovers) are mainly limited by thermal noise (AWGN). Benchmark performance tests for all communication systems (like receiver sensitivity tests) are conducted under AWGN assumptions.

Experiment Steps

  1. Thermal Noise: N0 = kT ≈ -174 dBm/Hz
  2. Noise Power: Pn = N0 + 10log(B) dBm
  3. SNR: SNR = Ps/Pn, determines signal quality
  4. Shannon Capacity: C = B × log2(1+SNR) bps
