| Abstract: | In allusion to the high computational complexity,low computational efficiency and large storage for direct FIR filtering and multi-interpolation filtering,in this paper,a multiple iteration filtering algorithm was studied to lower computational complexity and storage.The algorithm could generate fading coefficients in real-time.Its computational complexity was analyzed companing with other algorithm,and the simulation validated feasibility. |
| Keywords: | Watterson channel model multiple iteration filtering Doppler spread Gaussian power spectrum |
