提出了一种基于良好卷积码和比特交织器相结合的概念的次优网格编码方法。目的是提高衰落信道上数字无线电通信的可靠性。结果表明，在瑞利信道上并且对于固定的代码复杂度，所提出的系统优于基线系统。使用广义 R/sub o/ 和误码率上限来分析其性能。结果表明，在瑞利信道上，标准网格码可能不是提高通信信道可靠性的正确方法。讨论仅限于采用 8-PSK 调制的 2/3 速率编码系统。 >
A suboptimal trellis coding approach based on the concept of combining a good convolutional code and bit interleavers is presented. The aim is to improve the reliability of digital radio communication over a fading channel. It is shown that over a Rayleigh channel and for a fixed code complexity the proposed system is superior to the baseline system. Its performance is analyzed using the generalized R/sub o/ and the upper bound on the bit error rate. The results suggest that on a Rayleigh channel, the standard trellis codes may not be the correct approach for improving the reliability of the communication channel. The discussion is restricted to a rate 2/3 coded system with 8-PSK modulation. >
