ECHO CANCELLER HAVING KALMAN FILTER FOR OPTIMAL ADAPTATION |
| 摘要 |
Kalman filtering is applied to obtain a fast converging, low complexity echo (y(t)) canceller (18). An averaged diagonal Riccati equation allows optimal time varying adaptation gains K(t) to be precomputed, or computed online with a small number of scalar Riccati equations.
