A、 停等式ARQ,即Stop-and-waitARQ(SAWARQ) B、 后退N步ARQ C、 选择性重传ARQ,即Selection-Repeat(SR)ARQ D、 正比公平ARQ" 免费查看参考答案及解析 题目: PLC 的周期工作方式是 PLC 程序一旦 STOP 之后,是不断自动重复执行的,直到 RUN.程序的执行过程一般包括输入采样阶段、程序执行阶段和输出刷新阶段....
An error control protocol, Stop-and-Wait (SW), is modeled and simulated to demonstrate the efficiency of SimEvents. By being able to construct a novel control unit to manage packet flow for SW ARQ, the performance of an SW protocol is accurately evaluated under different scenarios. The ...
[0027] Dual-channel Stop-and-Wait ARQ [0028] Dual channel Stop-and-Wait ARQ offers a solution by parallelizing the stop-and-wait protocol and in effect running a separate instantiation of the ARQ protocol in the idle channels. As a result no system capacity goes wasted since one instance...

A recent publication describes an example of tunability in microstrip technology [22]. However, in contrast to microstrip, there has been not so much published research on tunable coplanar waveguide (CPW) [9,23–27] and tunable substrate integrated waveguide (SIW) [28–30] band-stop filters ...
