| Abstract: |
| LLMS(Leaky Least Mean Square) algorithm used to adaptive linear filters is generalized to blind decision feedback equalizer, and applied to blindly equalize the CCIR-549-2 "poor path" channels. Simulation results show the DD-LLMS(Decision Directed-LLMS) blind decision feedback equalization algorithm has better stability, fast convergence rate and good tracking ability. |
