在这个仿真模型，16
In this simulink model , 16-QAM modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal
is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset
can be seen by varying the phase of down-sampling
operation.The signal transmitted is recovered
at the detector output.-In this simulink model , 16-QAM modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal

LDPC pexit图分析
原模图分析译码门限值时，传统的EXIT不能用，所以采用pexit图，是原模图分析的最重要的工具。文中提出了一种新的外部信息转移分析方法，主要针对基于原模图和多边形的LDPC码 ，进一步介绍了边连接的限制，对于这一类的许多类型的码字，传统的EXIT图分析方法不能应用，文中提出的PEXIT图考虑了边的连接，允许对基于原模图的LDPC码的译码收敛估计，允许设计高结构化的接近容量的LDPC码
