Figure 5.13: BER vs. SNR plot for 16QAM 1/2 on different SUI channel
5.2.3 BLER Plots
BLER results play a very important role in the study of PHY layer performance analysis. Fig. 5.14, 5.15 and 5.16 show the BLER performance of all the modulation and coding profiles on SUI1, 2 and 3 channel models respectively. The results are consistent with the BER performance which we have observed in the previous section. In case of SUI1 channel condition, QPSK modulation requires 3dB more SNR for 1/4 code improvement at BLER level 102. The same amount of SNR is required for 1/4 code rate improvement for 16QAM modulation while 1.7 dB more SNR is required for 1/12 code r a t e i m p r o v e m e n t f o r 6 4 Q A M .
