语音信号短时分析
语音信号是时变。单个参数信号的改变比信号本身较缓慢。因此,对于此类参数的测量,显著较低的频率是信号的 ↗sampling 比 ↗sampling 频率的必要条件。帮助下窗函数的加权信号在时间域和分为局部信号序列进行了测量。关于测量的确切目标,必须确定"短时间分析"两个维度: 窗口长度 (加权部分信号长度) 和测量时间间隔 (帧速率,即各个窗口之间的距离)。
短时间分析操作
短时能量: 它是语音信号的强度。它反映了语音信号的振幅变化。
短时自相关函数: 自相关函数用于在函数中查找的周期性和
是很多的频谱分析方法的基础。
短时过零率: 短时过零率被定义为
次数的语音信号变化签署内给定
时间窗口。

ber_ofdm_with_amplifier
BER verses SNR in ofdm with amplifier:
The BER performances of OFDM systems over the AWGN channel are given
by the BER where N=512. We see that SNR required for BER=10-3
No channel coding scheme is adopted. Therefore, BER
is a bit higher. The results with 16 QAM show that the required Signal to Noise
Ratio (SNR) for BER=10-2 is almost the same. This is because the noise is the
dominant.
