项目摘要
For OFDM systems, number, location, and power distribution of pilot symbols are designed based on mean squared channel estimation error. The proposed method is applicable to OFDM-based cognitive radio with any null subcarriers. The sub-optimal location of pilot symbols is given by using cross entropy optimization that is a non-linear optimization technique. Pilot power distribution is determined by solving a convex optimization. Numerical simulations show that the proposed method outperformsthe conventional method.
对于OFDM系统,数字,位置和飞行员符号的电源分布是根据平方频道估计误差设计的。所提出的方法适用于任何无效子载波的基于OFDM的认知无线电。通过使用非线性优化技术的交叉熵优化给出了试验符号的亚最佳位置。通过求解凸优化来确定驾驶电源分布。数值模拟表明,所提出的方法优于常规方法。
