Title:
METHODS AND APPARATUS FOR CHANNEL ESTIMATION IN MIMO-OFDM COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/032244
Kind Code:
A2
Abstract:
A wireless receiver is configured to perform a method of channel estimation in a multiple input multiple output (MIMO) network. The method includes despreading a vector of received samples to determine an average channel estimate for each of a plurality of multiplexed layers associated with the MIMO network, canceling inter-layer interference using the average channel estimates for the layers and obtaining a time-varying estimate for each layer, and estimating the channel using a two-dimensional minimum mean squared error (2D MMSE) technique.
