ARQ的音标为[ɑːˈreɪk],基本翻译为“询问;确认;要求答复;确认书”。
速记技巧可以考虑使用发音类似的单词来辅助记忆,例如可以用“啊咧客”来速记。同时,理解其含义也很重要,它表示一种询问、确认的过程。在使用时,需要注意到字母Q在音标中的存在,它在这里代表的是元音字母。
ARQ这个词的英文词源可以追溯到拉丁语“Automatic Receiver Quadrant”,意为自动接收分机。这个词在英语中通常用于描述通信系统中用于接收信息的部分。
变化形式:在英语中,ARQ通常以复数形式出现,如“Automatic Receiver Quadrants”或“Automatic Receiver Quadrate”。
相关单词:
1. Retransmission:重传,指的是在ARQ过程中,当发送方收到接收方返回的错误信号时,会重新发送数据。
2. Acknowledgment:确认,指的是接收方在收到数据后,会向发送方发送一个信号,表示数据已成功接收。
3. Rejection:拒绝,与确认相反,指的是接收方在收到数据后,如果数据有错误或者不符合要求,会向发送方发送一个拒绝信号。
4. Automatic Repeat Request:自动重传请求,是一种通信协议,它允许发送方在数据被拒绝后自动请求重新发送数据。
5. Retransmission Protocol:重传协议,指的是使用ARQ机制的通信协议中的一种具体协议。
6. Forward Error Correction:前向纠错,是一种通信技术,它通过在发送数据时加入纠错码来提高数据的可靠性,而不是依赖于ARQ的重新传输。
7. Retransmission Delay:重传延迟,指的是ARQ机制中数据从发送到接收所需的时间。
8. Retransmission Failure Rate:重传失败率,用来衡量ARQ机制性能的一个指标,它表示在一定时间内数据成功重传的比例。
9. Retransmission Time:重传时间,指的是数据从发送到成功接收所需的时间。
10. Retransmission Window Size:重传窗口大小,指的是ARQ机制中用于存储待重传数据的窗口大小。这个窗口大小会影响ARQ的性能。
ARQ常用短语:
1. Automatic Repeat Request (ARQ) 自动重传请求
2. Forward Error Correction (FEC) 前向纠错
3. Hybrid ARQ (HARQ) 混合自动重传请求
4. Receiver-aided ARQ 接收器辅助的自动重传请求
5. Selective Repeat 选择重传
6. Selective Forwarding 选择转发
7. Retransmission Control Protocol (RCP) 重传控制协议
双语例句:
1. ARQ is a commonly used technique in wireless communication to improve the reliability of data transmission. 自动重传请求是无线通信中常用的技术,以提高数据传输的可靠性。
2. FEC and ARQ are two complementary techniques that can be used together to enhance the reliability of data transmission. 前向纠错和自动重传请求是两种互补的技术,可以一起使用来增强数据传输的可靠性。
英文小作文:
Automatic Repeat Request (ARQ) is a technique used in wireless communication to ensure reliable data transmission. By using ARQ, the receiver can request the sender to resend any lost or corrupted data packets. This helps to reduce the number of dropped packets and improve the overall quality of service.
One advantage of ARQ is that it allows for flexible error correction. Depending on the type of error, the sender can choose to resend a single packet, multiple packets, or even the entire message. This flexibility allows for more efficient use of resources and faster recovery from transmission errors.
Another benefit of ARQ is its simplicity and low cost. There is no need for complex error-detection schemes or additional signaling between the sender and receiver. Instead, ARQ relies on the reliable delivery of data packets over a wireless channel, which is typically reliable in most environments.
However, ARQ may not be suitable for all scenarios. For example, if the channel conditions are poor or if there are frequent transmission errors, other error-correction techniques such as Forward Error Correction (FEC) may be more appropriate. By combining ARQ and FEC, it is possible to achieve optimal performance in a wide range of environments and conditions.
