UEP Concepts in Modulation and Coding

Figure 4

SER performance in Rayleigh fading for the modified Hughes-Hartogs algorithm with adaptive hierarchical QAM assuming 3 different classes with a margin separation of 3 dB. In total, this figure has 6144 bits on 2048 subcarriers with two scenarios: 𝑇₀=1024, 𝑇₁=2048, 𝑇₂=3072, and 𝑇_𝑗=2048, 𝑗=0.2.
