| 摘 要： | 本评议提出了一个基于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全速率业务的信道进行了比较，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，仍然能保证传输的可靠性。

| Abstract: | 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 |
