摘要: 通过仿真研究了信道中的功率波动对低编码率Turbo码性能的影响, 结论认为在使用Turbo码的平衰落信道中, 影响性能的关键因素是衰落引起的码组功率波动, 每个码组内的符号功率波动相对来说影响不大.

关键词: 衰落信道, Turbo码, Nakagami

Abstract: Turbo code performance with channel power fluctuation is studied. The simulation results indicate that the decoding performance is primarily relied on power variation of code-block rather than the fading of code-bits.

Key words: Turbo code, fading channel, Nakagami
