Channel impulse response estimation using received signal variance |
摘要 |
The present invention proposes a device (1) for processing received signals transmitted via a transmission channel (4), said device comprising obtaining means (2a) adapted to obtain an estimated response function (h+e) of said transmission channel (4), based on said received signals (y); deriving means (2b) adapted to derive and estimated variance (delta2) of said received signals (y); and modifying means (2c) adapted to modify said estimated response function (h+e) by applying said estimated variance (beta2) to said estimated response function (h+e), thereby obtaining a modified impulse response (<highlight><uline>h</uline></highlight>). The present invention also proposes a corresponding method.
