Therefore , it is sure that this kind of codes will be promising in the future mobile communication . compared with traditional codes which are complex with long searching time , structured ldpc codes constructed by gragh rules or combinational algorithms can reduce the complexity and insure the performance , so they are potential in the future wireless communication system with theoretical value 傳統(tǒng)的ldpc碼的構(gòu)造采用計(jì)算機(jī)隨機(jī)搜索,耗時(shí)長,實(shí)現(xiàn)復(fù)雜,相比之下,利用圖論、組合代數(shù)等結(jié)構(gòu)化方法來設(shè)計(jì)ldpc能有效地降低構(gòu)造復(fù)雜度,并且保證了性能優(yōu)良,在未來移動(dòng)通信系統(tǒng)中是一種極有潛力的編碼方式。
