    • Disclosed are a code modulation method and apparatus for high order modulation. The method comprises: converting information that needs to be transmitted into a bit data stream, and demultiplexing the bit data stream into more than one channel of bit data stream; performing first-type coding on at least one channel of bit data stream in the more than one channel of stream, to obtain first output data; performing second-type coding on at least one channel of the remaining channels of bit data stream on which the first-type coding is not performed, to obtain second output data; and performing quadrature amplitude modulation on the first output data, to generate a modulation symbol for output. Compared with the prior art, the correctness rate of demodulation in the technical solution is improved significantly, achieving higher transmission efficiency.
    • 公开了一种用于高阶调制的码调制方法和装置。 该方法包括:将需要发送的信息转换成比特数据流,以及将比特数据流多路分解成多于一个信道的比特数据流; 在流的多于一个信道中的位数据流的至少一个信道上执行第一类型编码,以获得第一输出数据; 对未执行第一类型编码的比特数据流的剩余信道的至少一个信道执行第二类型编码,以获得第二输出数据; 并对第一输出数据执行正交幅度调制,以产生用于输出的调制符号。 与现有技术相比,技术解决方案的正确率明显提高,传输效率更高。
