Hi Dr.Schwarz,
My simulator is “Vienna LTE Simulators LTE-A Link Level Simulator, v1.3.”
Why is PMI_WB always zero in “ZFMUMIMO.m”? If PMI_WB is zero, we cannot get the precoding matrix because
“W = 1/sqrt(nLayers)*LTE_params.W1{nLayers}(:,:,PMI_WB)*LTE_params.W2{nLayers}(:,:,codebook_index(1)+1);”
in “LTE_common_get_precoding_matrix.m.”
Does it mean that PMI_WB is not implemented in “ZFMUMIMO.m”? If yes, have you implemented “PMI_WB” in the new version simulator?
Thank you.
