A Fading Channel Simulator Implementation Based on GPU Computing Techniques

Table 2

Time consumption by module computing 10 channel realizations.

Time (%)	Module
78.18%	Matrix-matrix multiplication
13.62%	Initializing random number generator^1
3.83%	FIR filter
2.37%	Upsampling
1.62%	Gaussian number generation
0.01%	Path gain

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