摘要
首先介绍了 L EE氏码对相位透明的多进制线性纠错码的性质 ,然后将它克服解调载波恢复相位模糊的应用从 PSK推广到 6 4QAM系统 ,并给出性能比较分析结果。
In digital radio transmission system, phase ambiguity is a usual problem encountered in demodulation. This paper introduces the characteristic and construction of a multi level linear error correcting code LEE code, which is transparent to phase ambiguity. A new way applying LEE codes to 64QAM system is also given. Finally the LEE code performance result is presented, compared with transmission system without FEC.
