- 直接序列扩频通信可以有效地抵抗来自信道中的窄带干扰。在一个直扩通信系统中,扩频是通过伪噪声序列(PN)对发送的信息数据进行调制来实现的。在接收端,原伪噪声序列和所收信号的相关运算可将窄带干扰扩展到DS信号的整个频带,使干扰等效为幅度较低频谱较平坦的噪声;同时,将DS信号解扩,恢复原始信息数据。-direct sequence spread spectrum communication can be effective resistance from the channel narrowband

- GPRS(General Packet Radio Service)是通用分组无线业务的简称。GPRS是GSM Phase2.1规范实现的内容之一,能提供比现有GSM网9.6kbit/s更高的数据率。GPRS采用与GSM 相同的频段、频带宽度、突发结构、无线调制标准、跳频规则以及相同的TDMA帧结构。因此,在GSM系统的基础上构建GPRS系统时,GSM系统中的绝大部分部件都不需要作硬件改动,只需作软件升级。-GPRS (General Packet Radio Service) is a Gen

- Gray Code是一个数列集合,每个数使用二进位来表示,假设使用n位元来表示每个数好了,任两个数之间只有一个位元值不同,例如以下为3位元的Gray Code: 000 001 011 010 110 111 101 100 由定义可以知道,Gray Code的顺序并不是唯一的,例如将上面的数列反过来写,也是一组Gray Code: 100 101 111 110 010 011 001 000 Gray Code是由贝尔实验室的Frank G
