چکیده
|
Orthogonal frequency-division multiplexing (ofdm) is an attractive transmission technique for high-bit-rate communication systems. one major drawback of ofdm is the high peak-to-average power ratio (papr) of the transmitter's output signal. a novel selected mapping (slm) scheme is proposed,which employs matrix transformation,cyclically shifting,and linear combining algorithm to generate new candidates. the novel scheme requires only one ifft and gets more candidate transmission signals throughout the entire process. the complexity analysis and simulation results show that this algorithm can dramatically reduce computational complexity comparing with the conventional slm scheme as in hill et al.,2000; yang et al.,2009; wang and ouyang,2005; li et al.,2010; and heo et al.,2007 under the similar papr reduction performance. © copyright 2011 tian-ming ma et al.
