A-Novel-Variable-Step-Size-NLMS-Algorithm-and-Its
By building the generalized Sigmoid function relationship between normalized step-size and the power of error signal,
a novel variable step-size NLMS algorithm is proposed. It is proved that the step-size of NPVSS-NLMS changes as
the new algorithm does when A=σv
-m and B=2. The physical meanings of the parameters in this algorithm are
explored. The theoretical analysis illustrate that this algorithm combine the virtues of NPVSS-NLMS and Sigmoid
function, and it leads to faster convergence rate and lower final misalignment. The computer simulation results
support the theoretical analysis.

mimo_ofdm_slm
In this paper, we present a Selected Mapping (SLM) PAPR reduction technique for MIMOOFDM
system with special protection of Side Information (SI). Selected Mapping (SLM)
is a powerful PAPR reduction technique since it does not cause any signal distortion and
simple to implement. As a special protection for the Side Information (SI) of SLM technique,
we propose a SI power allocation procedure. Simulation results show that our proposed
technique gives significantly better BER performance than the ordinary SLM technique for
MIMO-OFDM systems. Analysis for the optimum SI power allocation is also presented.
