Abstract--In this paper, a recursive least-squares (RLS) adap-
tive channel estimation scheme is applied for spatial modulation
(SM) system over a block fading multiple-input­multiple-output
(MIMO) channel. The performance of spatial modulation with
channel estimation is compared to vertical Bell Labs layered
space­time (V-BLAST) and maximum ratio combining (MRC)
transmission schemes for different pilot rates and a fixed 3-
b/s/Hz spectral efficiency. Computer simulations carried out
demonstrate the superiority of SM over V-BLAST and MRC
schemes. In addition, the results in this study show that SM is
more robust against channel estimation errors than the other
MIMO schemes.
