Abstract
In one embodiment, an apparatus for channel estimation includes a first receiver configured to obtain a first channel estimate associated with a communication channel between the apparatus and a user equipment. The apparatus also includes a second receiver. The second receiver includes a channel estimation unit and a normal receiver processing unit. The channel estimation unit is configured to compute a second channel estimate of channel conditions associated with the communication channel. The normal receiver processing unit is configured to compute weights using the second channel estimation unit. The channel estimation unit is further configured to obtain a delay between the obtaining of the first channel estimate and the computing of the weights, and to compute the second channel estimate using the delay and the first channel estimate.
