考虑到房屋内多种噪声，混响的影响，求出房屋的冲激相应(Taking into account a variety of house noise, reverberation effects, find the appropriate housing impulse)

Particle swarm optimization has been used to solve many optimization problems since it was proposed by Kennedy and Eberhart in 1995 [4]. After that, they published one book [9] and several papers on this topic [5][7][13][15], one of which did a study on its performance using four nonlinear functions adopted as a benchmark by many researchers in this area [14]. In PSO, each particle moves in the search space with a velocity according to its own previous best solution and its group’s previous best solution. The dimension of the search space can be any positive integer.

scrambling and descrambling

偏移四相移相键控调制，也就是OQPSK，输出信号为OQPSK调制信号的复包络(Offset four-phase phase shift keying modulation, that is, OQPSK, the output signal for the OQPSK modulated signal complex envelope)

here the matlab code is used for simulation of fading channels and convolutional codes

压缩包中自带资源卫星的tle，用matlab读取并绘制半长轴、轨道倾角、偏心率的变化曲线，观察期变化规律，文件读取的技巧很好！！(Compressed package comes resource satellites tle, using matlab to read and draw the semi-major axis , orbital inclination , eccentricity curve , variation of the observation period , file reading skills well ! ! )

将角度和幅度的二维数组画成dB值的polar图( POLARDB Polar coordinate plot. POLARDB(THETA, RHO) makes a plot using polar coordinates of the angle THETA, in radians, versus the radius RHO in dB. The maximum value of RHO should not exceed 1. It should not be normalized, however (i.e. its max. value may be less than 1). POLAR(THETA,RHO,S) uses the linestyle specified in string S. See PLOT for a description of legal linestyles. )
