CHANNEL ESTIMATION IN TD-SCDMA

摘要

Apparatus and methods for channel estimation in time division synchronous code division multiple access (TD-SCDMA), including determining least squares channel metric estimates based on a received signal that is received from one or more Node Bs, identifying signal taps and noise taps in a tapped delay line channel estimate based on at least one of temporal correlations and powers of the least squares channel metric estimates, and performing minimum mean square error scaling on the signal taps and the noise taps.
