摘要

1991年将在欧洲引进一种数字移动无线电系统,即所谓的集团特殊移动(GSM)系统。本文介绍了近年来GSM标准化的调制和编码技术。对于语音编码、信道编码和自适应均衡的基带处理算法,讨论了VLSI的要求。新系统的设计容量为欧洲约1000万用户。手持袖珍电话有望发挥重要作用。典型的要求是重量24小时,活动运行1小时。一个主要的问题是降低功耗,这需要在待机模式下关闭某些功能

Implementation aspects of the pan-European digital mobile radio system
In 1991 a digital mobile radio system, the so-called Group Special Mobile (GSM) system, will be introduced in Europe. The author presents the modulation and coding techniques which have been standardized recently For the GSM. for the baseband processing algorithms of speech coding, channel coding, and adaptive equalization, VLSI requirements are addressed. The new system has been designed for a capacity of about 10 million subscribers in Europe. Hand-held pocket telephones are expected to play a major role. The typical requirements are weight <0.8 kg, volume <900 cm, stand-by operation >24 h, and active operation >1 h. A major problem is the reduction of the power consumption, which requires that certain functions be switched off in the standby mode.<>
