    • Embodiments of the present invention disclose an ATCA data exchange system which includes: a backboard, at least one exchange board and service board. The exchange board includes at least one Fabric port group, each of which is connected to a service board through the backboard to form a first exchange channel for broadband service, the Fabric port group includes four difference sending and receiving port pairs, and each port pair includes a pair of difference receiving and sending ports. A connector 20 in the Fabric interface of the exchange board includes at least one port pair, and each port pair is connected to a service board through the backboard to form a second exchange channel and is configured for a separate narrowband service data exchange that is independent of the broadband data exchange. Thus to simplify the processing of narrowband data and to decrease the time delay.

    • A system for detecting a broadcast channel in a radio receiver includes a receive signal strength indicator (RSSI) element configured to develop an RSSI signal that is representative of a power in a desired channel, a switchable bandwidth channel select filter having a power detector configured to compare a power output of the desired channel and at least one channel adjacent to the desired channel to develop a signal to adjacent channel power ratio (SACPR) signal that is representative of the noise in the desired channel, and a seek element configured to determine whether the RSSI signal is greater than a predetermined RSSI threshold and configured to determine whether the SACPR signal is greater than a predetermined SACPR threshold.
    • 一种用于在无线电接收机中检测广播信道的系统包括:接收信号强度指示符(RSSI)元件,被配置为开发代表期望信道中的功率的RSSI信号;可切换带宽信道选择滤波器,具有功率检测器,被配置为 比较期望信道的功率输出和与期望信道相邻的至少一个信道,以产生表示所需信道中的噪声的相邻信道功率比(SACPR)信号的信号,以及被配置为确定是否 RSSI信号大于预定的RSSI阈值,并且被配置为确定SACPR信号是否大于预定的SACPR阈值。
