摘要
本文提出了一个基于GSM系统的高效数据传输方案。它采用RS码与TCM级联的编码调制结构替代GSM原有的GMSK调制方案 ,以提供 384kbit/s的数据业务 ,并引用相位校正单元以克服恶劣的无线传输环境所造成的相位噪声。该方案被集成在GSM平台上 ,并在典型的无线传输模型下与GSM的 96kbit/s全速率数据业务信道进行了比较 ,结果表明该编码调制方案在将编码调制效率提高一倍的前提下 。
This paper proposed a high efficient scheme based on GSM system Instead of GMSK,a concatenated structure is used with RS code as the outer code and 2/3TCM-8PSK as the inner one The novel link is designed to provide the data rate up to 384kbit/s To resist the phase noise in radio transmission,a phase adjusted unit is adopted The scneme has been integrated in GSM software simulation platform,and compared with GSM TCH/F96 channel over typical radio transmission models It is proved that the novel scheme can provide good performance with the data rate increased doubly
