(EN) Radio communication system employing spectral reuse transceivers
(ZH) 应用频谱再用收发器的无线电通信系统
الملخص
(EN)
A spectral reuse transceiver-based communication system conducts communications between a master site and a plurality of remote sites using a selected portion of a communication bandwidth containing a plurality of sub-bandwidth channels. Each remote site transceiver monitors the communication bandwidth for activity on the sub-bandwidth channels, and informs a master site transceiver which sub-bandwidth communication channels are absent communication activity and therefore constitute clear channels. The master site transceiver compiles an aggregate list of clear channels from all the remote sites and then broadcasts the aggregate list to the remote sites. The master site and a remote site then conduct communications therebetween by frequency-hopping and/or orthogonal frequency multiplexing among the clear channels using an a priori known PN sequence.

(ZH)

一种频谱再用收发器为基础的通信系统,用含有多个子带宽信道的通信带宽的选择部分,进行在主站和多个远程站之间的通信。每个远程站收发器监视所述通信带宽在所述子带宽信道上的活动,并通知主站收发器,哪个子带宽通信信道不存在通信活动,并由此构成纯信道。所述主站收发器从所有所述远程站汇编纯信道的集合列表,并然后,将所述集合列表传播给所述远程站。然后,用一个事先已知的PN序列,通过所述纯信道内的跳频和/或正交频分多路复用,然后所述主站和远程站在其间进行通信。
