Channel estimation where at least two sets of multipath components for a reception range are formed by applying spatial filtering to reference signal information measured by a communication device. Each set of multipath components comprises a number of multipath components that is less than the number...
Channel estimation is a special case of the system identification problem that has a long history in the field of signal processing. The most common method to estimate a channel at the Rx is based on a training sequence (i.e., a data-aided scenario). The strategies below explain the funda...

PER-CELL TIMING AND/OR FREQUENCY ACQUISITION AND THEIR USE ON CHANNEL ESTIMATION IN WIRELESS NETWORKS A method, an apparatus, and a computer program product for wireless communication are provided in which a system timing is estimated, derived from timing of one or more cells, a timing offset ...
The estimation of channel delays along with channel attenuation and phases of different users constitutes the first stage in the detection process at the receiving base station in a CDMA communication system. This stage, called channel parameter estimation, forms the bottleneck for the detection of ...
Channel Estimation for Wireless OFDM Communications 19 1.5 System description and signal modelling The primary idea behind OFDM communication is dividing an occupied frequency band into many parallel sub-channels to deliver information simultaneously. By maintaining ...
