本文提出了一种用于陆地移动通信的具有删截卷积码的自适应调制系统，以在多径衰落环境中实现高质量、高比特率和高频谱效率的数据传输。所提出的系统根据瞬时衰落信道条件自适应地控制删截卷积码的编码率、符号率和调制级别。通过理论和计算机模拟评估衰落环境中的性能。结果表明，与传统的自适应调制系统相比，所提出的系统可以实现更高质量的传输，而不会降低平均比特率。
This paper proposes an adaptive modulation system with a punctured convolutional code for land mobile communications to achieve high quality, high bit rate, and high spectral efficient data transmission in multipath fading environments. The proposed system adaptively controls the coding rate of the punctured convolutional code, symbol rate, and modulation level according to the instantaneous fading channel conditions. The performance in fading environments is evaluated theoretically and by computer simulation. The results show that the proposed system can realize higher quality transmission without the degradation in average bit rate compared to conventional adaptive modulation systems.
