Table 2

Time consumption by module computing 10 channel realizations.

Time (%)Module

78.18%Matrix-matrix multiplication
13.62%Initializing random number generator1
3.83%FIR filter
1.62%Gaussian number generation
0.01%Path gain

The seed initialization is carried out only once before the first channel realization.
