交织码通常表示为（M，N），分组长度L=MN，交织方式用M行N列的交织矩阵表示。一般，交织方式分为分组交织和卷积交织。分组交织的交织矩阵按列写入，按行读出；去交织矩阵按行写入按列读出。卷积交织的交织矩阵和去交织矩阵的写入与读出均按行进行。(Intertwined code is usually expressed as (M, N), the packet length L = MN, interwoven manner, said interwoven matrix with M rows and N columns. In general, interwoven into the packet interleaving and convolutional interleaving. Grouping of interwoven interwoven matrix column to write, to read de-interlacing matrix read out by column written by line by line. Convolutional interleaving interleaving matrix and de-interlacing matrix to write and read are OK.)

DFT进行频谱分析时的三种现象
1、混叠：对连续信号采样，要求连续信号是带限的，采样频率要足够高。Fs应满足Nyquist采样定理才不产生混叠。
采样前加低通滤波器防混叠
2、频谱泄漏：DFT对时域信号进行了截断（相当于采样信号乘了一个窗函数），时域的乘积相当于频域卷积，改变了原信号频谱。
改用其他窗函数（非矩形）改善泄漏。
3、栅栏现象：DFT 只给出了频谱在采样点上的取值，采样点间的频谱内容丢失。(DFT spectrum analysis of a three phenomena, aliasing : continuous signal sampling, requiring continuous signal is band-limited, the sampling frequency should be high enough. Fs meet the Nyquist Sampling Theorem would not have aliasing. Sampling former low-pass filter plus anti-aliasing 2, spectrum leakage : DFT right time domain signal a disconnect (equivalent to a sampling signal by a window function). time domain is equivalent to the product of frequency-domain convolution, changes in the spectrum of the original signal. Window functions to switch to other (non-rectangular) to improve leakage. 3, fenced phenomenon : DFT spectrum is given only at the sampling point value, sampling points of the spectrum as lost.)
