In this letter, we investigate a decimated selective mapping (SLM) method for the peak-to-mean envelope power ratio (PMEPR) reduction in an OFDM system. Under the condition of the same side information (SI) bits, the SLM can be implemented by decimating OFDM samples, which is less complex compared to the ordinary SLM incurring a slight degradation of the PMEPR performance. The decimated SLM (DSLM) approach can be generalized to a multiple-antenna OFDM system employing a space-time block coding (STBC).
