Research and implementation of a new crc coding algorithm 編碼算法研究與實現(xiàn)
The theory of extended shortened codes is a complement of the theory of the common crc codes 擴展縮短碼的理論是原crc碼理論的完善和補充。
Extended shortened crc codes and nonlinear extended shortened codes are studied in the paper 本文分別研究了擴展縮短crc碼和非線性擴展縮短碼。
I also studied some related technologies , such as dvb system , atm technology , interleave technology , crc code technology 并研究了用到的多種技術,主要涉及到dvb系統(tǒng)、 atm技術、交織技術、 crc編碼技術。
First , the thesis introduced conception and characters of software radio ; second , the thesis analyzed architectures of software radio ; third , the thesis discussed critical technologies of software radio and applications of dsp in software radio , moreover , realized arithmetic of crc coding , convolution code , orthogonal digital frequency conversion and multi - speeds signal process ; finally , the thesis prospected foreground of software radio 本文首先介紹了軟件無線電的概念和特征,接著分析了軟件無線電體系結構,論述了軟件無線電的關鍵技術及dsp在軟件無線電中的應用,在tms320c54x上實現(xiàn)了crc編碼、卷積碼,完成了正交數(shù)字變頻和多速率信號處理的dsp算法,最后展望了軟件無線電的應用前景。
The implementation of crc - rs decoder in the project asks for an adoption of rs and extended shortened crc codes . although extended shortened crc codes have been used e xtensively i n c ommunication sy stems , t he r elative d ocuments o n t he c odes a re little . thus , on the basis of the common crc codes , the paper brings forward a concept of extended shortened crc codes 本論文內容來源于某通信設備研制項目,該項目中的“ crc - rs譯碼器的設計”要求采用rs和擴展縮短crc碼來實現(xiàn)。對于擴展縮短crc碼使用多,但有關的研究文獻很少。由此,論文在原有crc碼的基礎上提出了擴展縮短碼的新概念。
