摘要
Abstract
In Helicopter Satellite Communication System( HSCS) , the rotor shield will result in the deterio-rative performance of the system. The codes can be partly punctured by the rotor shield and it is an impera-tive problem. Through the analysis of the punctured Turbo codes, a new interleaver which can be well ap-plied in this system is proposed. The characters that the interleaver satisfies include ( 1 ) dispersing the punctured code chips among all the chips and turning burst errors into random errors,(2) both systematic and parity outputs of the same information bit should be deleted only one bit,(3) reserving the neighbor-hoods of the punctured bit field,(4)the punctured bits should folow the cycle model of systematic bit-the first parity bit-the second parity bit. Finally,comparison between the new pattern interleaver and the con-ventional ones shows that the former one makes the code’s bit error rate( BER) performance obtain more a-melioration and improves the HSCS’communication reliability.关键词
