This paper presents a novel scheme to transmit signals in a Multiuser Multiple-Input Multiple-
Output (MU-MIMO) downlink scenario. The proposed scheme combines Block
Diagonalization (BD) and Generalized Spatial Modulation (SM) Techniques. The SM
technique is used to add a broadcast transmission to the conventional MU-MIMO BD
scheme, which results in a novel BDSM proposal. We compare the proposed BDSM scheme
with the conventional BD scheme considering the Bit Error Rate (BER) performance …
