PID控制极点配置的自适应控制的应用实例(PID control poles of adaptive control)

基于光正交码构造了一类新的不规则00c—LDPc码．新的LDPC码是准循环码，其编码复杂度与码长成 线性关系，具有编码复杂度低的特点，它所对应的双向图中没有四线循环．用和积译码算法对新的码字进行了仿 真，结果表明，与具有类似参数的随机码和规则OOc—LDPc码相比，当信道误码率为10。5时，译码增益分别为 0．3和0．15 dB．(Construct a new class of irregular the 00c-LDPc code based on optical orthogonal codes. LDPC codes are quasi-cyclic code, its complex coding with code length linear relationship, with low encoding complexity, the corresponding bidirectional Figure it in four-wire loop. Simulation with integrated decoding algorithm of the new code word, the results show that when the channel bit error rate, compared with the random codes with similar parameters and rules OOc-LDPc code decoding gain were 10.5 0.3 and 0.15 dB.)
