3) BPCS Broadband Personal Communication Service
宽带个人通信服务
4) multi-chirps jamming
多个宽带Chirp干扰
1.
Based on the impulse characteristic presenting the Chirp jamming in the FRFT domain, the identification and excision for the multi-chirps jamming in DSSS communications system is proposed, which implements FRFT for received signal and then searches and eliminates the local maximum above a threshold, and then makes invert FRFT so that the interference is identified and removed one by one.
根据宽带Chirp干扰信号在与其调频斜率一致的分数阶傅里叶变换域呈现冲激函数特征,对接收的信号进行连续阶数的分数阶傅里叶变换,在适当的阈值下搜索并剔除其局部极大值后再进行反变换,从而对直接序列扩频通信系统中多个宽带Chirp干扰逐一识别和剔除,该方法计算量适中,且对干扰的强弱有较大的适应范围,仿真实验结果证明了这种方法的有效性。
5) BIP-ISDN Broadband,Intelligent and Personalized Integrated Services Digital Network

补充资料:宽带和窄带业务
宽带业务是相对窄带业务而言的,一般来说,对于速率低于2Mb/s的通信业务统称窄带业务,如电话网、N-ISDN所提供的业务。对于高于2Mb/s的通信业务,如帧中继业务、视频点播、ATM业务、TV会议等称为宽带通信业务。 目前投入应用的宽带接入技术主要有两种:ADSL和FTTX+LAN。
