H infinite transfer alignment
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. ()

BPSK调制仿真
bpsk调制仿真，可直接用 1、数字调制方法数字调制就是把数字基带信号的频谱搬移到高频处，形成适合在信道中传输的带通信号。基本的数字调制方式有振幅键控（ASK）、频移键控（FSK）、绝对相移键控（PSK）、相对（差分）相移键控（DPSK）。在接收端可以采用想干解调或非相干解调还原数字基带信号。数字信号的传输方式分为基带传输和带通传输。然而，实际中的大多数信道（如）无线信道具有丰富的低频分量。为了使数字信号在带通信道中传输，必须用数字基带信号对载波进行调制，以使信号与信道的特性相匹配。(1, digital modulation method Digital modulation is the transfer of the spectrum of a digital baseband signal to a high frequency to form a bandpass signal suitable for transmission in the channel. The basic digital modulation methods are amplitude keying (ASK), frequency shift keying (FSK), absolute phase shift keying (PSK), and relative (differential) phase shift keying (DPSK). At the receiving end, the digital baseband signal can be restored by using dry demodulation or non-coherent demodulation. Digital signal transmission methods are divided into baseband transmission and bandpass transmission. However, most channels in practice, such as wireless channels, have rich low frequency components. In order for a digital signal to be transmitted in a band channel, the carrier must be modulated with a digital baseband signal to match the signal to the characteristics of the channel.)
