用split-step方法求解非线性薛定谔(NLS)方程的例子(This code solves the NLS equation with the split-step method)

In this paper, we have proposed a new PAPR reduction technique in MIMO-OFDM systems. It achieves the result which proves the PAPR of 2×2 MIMO-OFDM systems. The parameters of the simulation are determined by standard IEEE 802.11n. From the simulation results, it is shown the proposed method has better PAPR performance in this system. Additionally, when the number of sub-blocks is increased, high PAPR reduction performance can be obtained.
