5.2.7 Spectral Efficiency
The spectral efficiency of all the modulation and coding profile on SUI1 channel model is shown in Figure 5.38. The spectral efficiency is presented in many ways in the literature. We derived the spectral efficiency using the relation ,
= ( 1pe )n mr
Here, Pethe bit error rate n the number of bits in the block m the number of bits per symbol and r the code rate
Figure 5.39 shows the spectral efficiency of QPSK ¾ on SUI1, 2 and 3 channel models.
