Multiple input multiple output techniques combined with orthogonal frequency division multiplexing (MIMO-OFDM) provide a promising approach for wireless systems. However, a serious drawback of the OFDM system is the high peak-toaverage power ratio (PAPR), which may severely affect the power efficiency of RF power amplifiers. In this paper, we propose a simple method to reduce the PAPR of MIMO-OFDM signals based on the use of unused subcarriers. Instead of processing the signals at each transmitter separately, a peak cancelling signal is generated at one antenna and is then applied to all the others with only simple modifications. Simulation has shown that a minimum 2 dB reduction in PAPR can be achieved for all transmit signals using this approach. As the signal processing is nearly all done at a single transmitter, repetition of the operations at each transmitter is avoided, and therefore the overall cost of the system can be significantly reduced.

从实际应用的角度出发，提出利用跟踪微分滤波器抑制机冀挠曲变形产生的影响，通过杆臂效应补偿消 除干扰加速度，用延时补偿算法减少由数据传输延迟造成的量测信息误差。在此基础之上，采用“速度+姿态” 匹配方案，研究了基于H_滤波估计的快速传递对准方法.大量数值仿真、静态试验、动态跑车试验表明，这 些方法有收敛速度较快、精度较高的特点，并t,有较强的抗干扰能力。试验也验证了传递对准方法的有效、可 行，能满足控制系统对导航信息的精度要求. ()
