In this paper, the effect of pulse shaping in the spatial modulation (SM) method is investigated. In the SM, extra bit transmission is transmitted by selecting the active antenna in each symbol transmission, thus increasing the spectral efficiency. However, active antenna switching in each symbol transmission causes clipping in the signal if the transmitted pulse is span outside its time duration. The effects of the filter span and the roll-off factor on the SM bit error rate were investigated by Monte Carlo simulation. In the simulations, it has been observed that the low roll-off factor value and low filter span increase the bit error.
