In the next generation of wireless communication , the application of mimo technologies increases the system capacity linearly with the minimum number of transmit and receive antennas 在新一代的移动通信中, mimo技术的应用使得系统的容量随发射和接收端的最小天线数目的增加而线性增加。
The digital base - band cdma transmitting and receiving scheme is put forward . the scheme uses a technique called as zero medium frequency without the need of pn codes synchronously are resumed 提出了具有免伪码同步恢复、免载波同步提取、免位同步的零中频cdma数字基带发送、接收方案。
When non - reciprocal phase shifters are used , it is necessary to change the phase - shifter setting between transmit and receive to maintain the same phase shift on receive as was used on transmission 当使用非互易移相器时，必须要在发射和接收之间改变移相器设置来保持接收相移与发射的一致。
With the development of the practice on the fieldbus control system , we can see that the cable transmission cannot reach the demand of varied data transmitting and receiving on the industrial fieldbus 随着工业现场总线研究和应用的飞速发展，单一的有线传输方式已不能满足现场级设备传输数据的要求。
The serial control implements transmitting and receiving data under the rs232c protocol . the serial control is standard input and output equipment of powerpc ~ ( tm ) 405 embedded in fpga 串口控制器实现了兼容rs232c协议的串口异步发送和接收数据的功能,它是powerpc ~ ( tm ) 405和计算机进行通信的硬件基础。
The low - power , silicon microchip radios in the devices can transmit and receive data about as fast as a dial - up modem , but their range is limited to less than 30 meters ? sometimes much less 尘粒内的低功率矽晶片无线电，发送与接收数据的速度大约和拨接数据机一样，但是作用距离却不到30公尺，有时还会更短。
At same time , it was also investigated the impact of the position errors of multiple antennas both sides of transmit and receive on the correlation of antenna array , and the simulation results by computer are also given 同时还研究了多天线的位置误差对天线阵列的相关函数的影响，给出了有关仿真结果。
They transmit and receive radio waves , set the timing of our quartz watches and our computers . crystal has been a favored gemstone for centuries because of its beauty and its practical use as an energy conductor 白水晶透明无色，晶莹通透，白色是红橙黄绿蓝靛紫所有关塞光色的综合体，代表著平衡和美满。
Under the concept of software defined radio , this dissertion brings forward a solution of the fsk modulation and demodulation fit for the transmitting and receiving of the railway control signal 从系统角度着眼,在软件无线电概念的框架下,结合理论基础提出了适用于列车控制信号发送与接收的fsk信号调制解调方案。
For web sites that process payment transactions , the web server also supports secure sockets layer ( ssl ) , the internet protocol for transmitting and receiving information securely over the internet 对于处理支付交易的网站，网络服务器也支持加密套接字协议层( ssl ) ? ?用于在因特网上安全地传输与接收信息的因特网协议。
