EDGE
关于EDGE功能的描述，以下不正确的是（）
A:在RF层增加了8PSK调制方式，使得单信道最大速率可达59.2kbit/s B:每信道捆绑额外３条16K子时隙以达到EDGE理论速率 C:目前EDGE功能不支持双时隙和ABIS接口卫星传输 D:如果不用EDGE功能，EDGE载频只需加载普通载频版本即可
下列EDGE系统哪些说法是正确的（）
A:EDGE系统的信道编码方式的数据传输速率都比GPRS系统的高 B:EDGE系统的信道编码方式的数据传输速率都比GPRS系统的低 C:EDGE系统采用8PSK调制的信道编码方式所要求的C/I一定比采用GMSK调制的高 D:EDGE系统采用8PSK调制的信道编码方式所要求的C/I不一定比采用GMSK调制的高
GPRS/EDGE系统的PDCH信道数量规划中，需要下列哪些数据：（）
A:移动用户数； B:GPRS/EDGE用户渗透率； C:单用户数据业务量； D:数据业务的GOS。
以下关于华为EDGE说法，正确的有（）
A:支持MCSX编码的动态调整，支持对站点空闲时隙的动态配置和动态管理 B:支持EDGE载频的主B互助功能 C:仅支持EGPRS，不支持ECSD D:EDGEBTS目前不支持PBU配置
EDGE比GPRS能提供更高数据传输速率的原因有：（）
A:EDGE可以使用8PSK调制方式 B:LQC可以使用LA和IR C:EDGE能提高C/I
关于EDGE，下面哪个是错误的（）
A:为支持EDGE，需要在构成GPRS网络的PCU、BTS进行重新开发，BSC不用 B:EDGE包括EGPRS和ECSD两种业务，我司采用业界普遍的EGPRS业务支持EDGE C:EDGE系统通过在Um口增加PSK调制方式提高单时隙数据传输能力，通过多时隙捆绑方式提高单用户的数据传输能力 D:PCU和BTS支持新的MCS1～MCS9编解码
Oxford is a very old town on the River Thames, about 60 miles from London. Unlike modern university towns, where you usually find the university on the edge of the town, or on its own campus (校园), Oxford’s center is the university; and all around the crossroads at the very heart of Oxford, Carfax, there are grey stone colleges and other university buildings. In the center you can also find interesting old restaurants. There are a lot of churches, and a few really large and interesting buildings, such as the Ashmolean Museum, the "round" library, the Bodleian and Radcliffe Camera. Like all English towns, there are parks, and one" The Parks" is the home of university cricket(板球) in the summer months. As you leave the center and go towards the edge of Oxford you can see industrial areas in one direction; and in another, beautiful suburbs(郊区). There is, in fact, quite a lot of industry in Oxford.
Visitors to Oxford will find that ______.
A:the university is also the town center B:one of the crossroads is called Carfax C:the university is on the edge of the town D:most buildings are modern and interesting
