TRANSMISSION AND RECEPTION OF SIGNALS IN COMMUNICATION SYSTEMS |
摘要 |
<p>From a mobile station (125) a signal is sent that is compatible with a first communication system and at the same time a further signal is sent compatible with another communication system. The further signal is received and processed by a base station (136). Components in the mobile station are provided for sending a narrow band signal (AMPS) during communication with a spread spectrum communication system. The latter has code-division multiple access (CDMA). Components are available for processing the narrow band signal for the purpose of communication transfer in the mobile station (125) from the spread spectrum communication system to a narrow band communication system. Other mobile stations which send a spread spectrum signal refrain from transmission while the mobile station (125) is sending a narrow band signal (AMPS).</p> |
