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.)

LDPC
LDPC码是通过校验矩阵定义的一类线性码，为使译码可行，在码长较长时需要校验矩阵满足“稀疏性”，即校验矩阵中1的密度比较低，也就是要求校验矩阵中1的个数远小于0的个数，并且码长越长，密度就要越低。
(LDPC Coding with PSK modulation in Rayleigh fading channel
Most of the functions are built in matlab functions found in the comm. toolbox. These can also be easily configurable in the code to meet your requirements.
In the given code, set the SNR, codeRate, modulation order (psk) and Number of frames to be simulated.
Please feel free to contact me and let me know your comments.
