脉冲编码调制(PCM)实现
编程实现PCM技术的三个过程:采样、量化与编码。
采样:低通连续信号采样,以 x=sin(200*t) m=x./(200*t) m=m.*m 为例说明低通采样定理,绘出信号时、频图形;带通连续信号采样,以x=sin(20*t) m=x./t 为例说明带通采样定理,绘出信号时、频图形。
量化:均匀量化,以幅度 的正弦信号为例实现为64级电平的均匀量化;非均匀量化,输入A律PCM编码器的正弦信号 ,采样序列为 ,将其进行PCM编码,给出编码器的输出码组序列
编码:以上述信号为例,实现A律的13折线近似法及国际标准PCM对数A律量化编码。(Pulse code modulation (PCM) to achieve
PCM technology programming three processes: sampling, quantization and coding.
Sample: low-pass continuous signal sampling to x = sin (200* t) m = x./(200* t) m = m.* m an example low-pass sampling theorem, draw the signal, frequency graphics bandpass sampling continuous signals to x = sin (20* t) m = x./t an example bandpass sampling theorem, draw the signal, frequency graph.
Quantization: uniform quantization, in order to realize the magnitude of sinusoidal signal as an example for the 64 level uniform quantization non-uniform quantization, input A law PCM encoder sine signal, the sampling sequence, to be PCM encoded, the encoder is given The output code sequence
Code: A Case Study of the signal to achieve the 13 A line approximation law and international standards on the number of A law PCM coding quantization.)

1Channel-EstimationMIMO
无线衰落信道
在无线移动信道中,信号从发射天线经过复杂的传播环境到达接收天线,接收信号为各反射、衍射和散射分量以及信道噪声的复合,因而会产生严重的失真。另外,移动信道中由于移动台运动或信道环境的改变会使信道特性随时间随机变化,接收到的信号由于Doppler效应会产生更为严重的失真。
