ofdm-qpsk-mycreatechannel
我们将通过MATLAB仿真在发送平均功率和传输速率相同的情况下,在传输特性为理想的平的和非平(即存在码间干扰)的信道上,对多载波OFDM和单载波QPSK的误码率进行比较。(We will send the average power by MATLAB simulation and the transmission rate in the same circumstances, in the transmission characteristics of the ideal of peace and non-flat (as is the inter-symbol interference) of the channel, multi-carrier OFDM and single carrier QPSK BER rates were compared.)

cylinder2
[X,Y,Z]=cylinder2(x,y,z,r,N,o)
向量X,Y,Z轴定义圆柱面中心线
和矢量r定义圆柱面半径,并已
为的x,y,z的长度相同
N是周围围点的数量。默认值
为N= 100。
Ø 定义了矩阵圆柱generatix(圆圈)椭圆
表面。其内容以0和1之间的值,并适用于
小学和中学的母线轴。值的defeault
Ø =的(长(x),2)。
矩阵X,Y,Z轴确定圆柱面,冲浪(的X,Y,Z)的显示器
圆柱面。( [X,Y,Z]=cylinder2(x,y,z,r,N,o)
Vectors x, y, z define the central line of cylindrical surface
and vector r defines the radius of cylindrical surface, and has
the same length as x, y, z.
N is the number of points around the circumference. The default value
is N = 100.
Matrix o defines ovality of the generatix (circle) of cylindrical
surface. Its elements take values between 0 and 1 and apply to the
primary and secondary axis of generatrix. The defeault values are
o=ones(length(x),2).
Matrices X, Y, Z define the cylindrical surface, surf(X,Y,Z) displays
the cylindrical surface. )

ding
选取windows系统自带的ding.wav信号作为分析对象,在Matlab软件平台下,利用函数wavread对音频信号进行采样,记住采样频率和采样点数,听一下原始声音sound(y, fs, bits)。
(2)音频信号的频谱分析,先画出音频信号的时域波形;然后对音频号进行快速傅里叶变换fft(y,N),N取32768,画出信号的频谱特性,加深对频谱特性的理解。
(3)根据频谱,反演时域特性,画出时域波形。寻找幅值最大的两个频率,此频率除以fft点数在乘以采样频率就是信号的主频,即可合成信号的时域图形,听一下声音。
(4)对原音频信号进行1024点的分段付立业分析meshgrid
(5)根据主要频线合成音频,并画出时域图形,试听合成效果。
(6)采用线性插值(linspace)和傅立业反变换(fliplr, ifft)分别合成音频,并画出时域图形,试听效果。
