Let's write something that USES basic frequency analysis to decode an encoded message.

让我们编写一些程序以使用基本频率分析将编码信息解码。

Finally, the initial threshold is identified and relation matrix is constructed, and the wavelet coefficients of the high frequency subbands are encoded progressively by using relation matrix.

首先确定初始阈值，并构造小波系数的关系矩阵，然后结合关系矩阵对高频子带系数进行逐次逼近量化编码。

As a result, a sequence of encoded data stream having a lower number of bit transitions with respect to the frequency of signal transitions of the data stream prior to the encoding is generated.

结果，生成编码后的数据流序列，其相对于编码之前数据流的信号跃迁频率具有更低的位跃迁数目。

At the time, prosecutors allege, Mrs Heidrun was sitting in her study in front of a wireless transmitter that was receiving encoded messages on a shortwave frequency and was hooked up by cable to a computer, reports the German news website Spiegel Online.
