Blind-Signal-Separation
This paper presents a new algorithm to extract
the fetal ECG from an ECG recorded on the
mother’s abdomen. The algorithm consists of
two steps: first, ECG of fetus is extracted from
the original signal using a two-level wavelet
transform. We use Daubechie wavelet transform,
which is similar in shape to heart beat wave. The
resulted signal is then low-pass filtered using the
Savitzky-Golay smoothing filter to attenuate the
effect of noise. The filtered signal is considered
as the fetal ECG. The algorithm was applied on
both synthetic and real ECG signals. The results
in this paper show that the proposed algorithm
has promising performance.

FSK
数字频带通信系统
输入:首先输入模拟信号,给出此模拟信号的时域波形。
数字化:将模拟信号进行数字化,得到数字信号,可以选择PCM编码。
调制:可以选择简单的二进制数字调制方式。例如振幅键控(2ASK)、相移监控(2PSK)、频移键控(2FSK)、差分相移键控(DPSK)等。要求每个题目至少选择两种调制方式。有能力的同学也可以选择其它高效的调制方式?例如多进制数字振幅键控等?给出调制后信号的时域波形。
信道:假定信道属于加性高斯信道?或自行设计。
解调:相应的2ASK、2PSK、2FSK、DPSK解调,仿真获得解调输出波形。
PCM解码:给出解码后的模拟信号的时域波形,并与输入信号进行比较。
系统性能分析:比较在不同调制方式下,该数字频带传输系统的性能指标,即该系统的输出误码率随输入信噪比的变化曲线。(Digital frequency band communication system)
