Abstract
A method for estimating memory-enabled transmission channels, having the following steps: determining a first estimation ĥ of the pulse response of the transmission channel; estimating the additive interferences of the transmission channel; and correcting the first channel estimation while taking into consideration the estimation of the additive interferences. The first channel estimation is performed using a matched filter or a least squares estimation.
Claims12
A method for estimating a memory-enabled transmission channel, comprising the steps of:
- determining a first estimation ĥ of a pulse response of the memory-enabled transmission channel;
- performing an estimation of an intensity level σ2 of an additive interference of the memory-enabled transmission channel;
- and
- performing a correction of the first estimation of the pulse response by taking into consideration the estimation of the intensity level σ2 of the additive interference of the memory-enabled transmission channel, wherein an amount of correction of the first estimation varies depending on the estimated intensity level σ2 of the additive interference.
