摘要
针对无线通信课程中纠错编码部分在教学中存在的问题,探讨用Microsoft Visual C++6.0编程软件进行辅助实验教学。低密度奇偶校验码(LDPC)由于其较好的纠错性能而得到学术界的广泛关注。本文通过开发LDPC码的交织技术在抗击衰落信道中的实验,编写其中的相关程序并仿真,使学生更深入地理解纠错编码原理。这样,通过实验教学方式调动学生的学习积极性,提高学生的实验动手能力,从而提高了教学质量和教学效果。
Considering some problems that exist in error correction coding when teaching the curriculum of wireless communications, we probes into the idea of using Microsoft Visual C ＋ ＋ 6. 0 programming software to carry out auxiliary experimental teaching. Low - density parity - check （ LDPC） codes with excellent error -correcting performance draws extensive interests in the academic circles. In this paper, we design experi-ments about the interwoven technology of the LDPC code applied in the resistant fading channel, write the rel- evant procedures and simulation, and then make students have a better understanding of the principle of error correction coding. Therefore, through experimental teaching method, we can stimulate students＇leaming activity, improve their experimental practice ability, in order to promote the quality and effect of teaching.
