摘要
目前的GSM无线接口中使用了慢速跳频技术,有效地改善了无线信号的传输质量。本文研究了慢跳频对GSM系统掉话的影响,并给出了跳频对掉话改善的分析。
At present,with the use of slow frequency hopping technology in GSM radio interface,quality of radio signal is greatly improved. The paper analyses the influence of GSM system fall speech on SFH and puts forward a table of statistics of SFH.
