Abstract
A transmitter includes a layer mapper and a precoder. The layer mapper is configured to map 2 codewords to 3 layers to output a mapped set of 3 symbols. A first codeword is mapped into one layer, and a second codeword is mapped into two layers. The precoder is configured to precode the mapped set of 3 symbols using a precoding matrix that distributes the mapped set of 3 symbols across 4 antenna ports so that each codeword is distributed across 2 antenna ports.
