Interpolation based channel estimation (IBCE) is recently carried out by transmitting known pilot symbols in given positions of the frequency-time grid for spatial modulation and orthogonal frequency division multiplexing (SM-OFDM) systems. It is known that the iterative channel estimation techniques provide substantial gain over non-iterative methods when the total number pilots are not sufficient...
Recently, spatial modulation (SM) and space-time block coding (STBC) are combined to take advantage of the benefits of both while avoiding their drawbacks for multiple-input and multiple-output (MIMO) systems. The pioneering works on STBC-SM assume that perfect knowledge of the channel fading coefficients is available at the receiver. This work1 addresses the challenging and timely problem of channel...
