ABSTRACT:
In accordance with an embodiment of the present invention, a novel system and method for MMSE channel estimation are provided that take synchronization errors, either intentional or unintentional, into account during the channel estimation process. The proposed channel estimation in accordance with the present invention improves the noise averaging capability and takes advantage of channel correlation fully by removing the effect of synchronization errors during the estimation process.
