speed coding meaning in English
快速编码
Examples
- The basic principle of ofdm is converting high speed codes flowing in serial transmitting into low speed codes flowing in parallel transmitting , so the period of code is lengthened . it get over multi - channel delay using protective interval . if we deal with the received codes appropriately in receiver , the multi - channel can be matched with single channel , and the effect of channel to signal become multiplication from convolution , so ofdm can eliminate isi effectively
Ofdm的基本原理是将高速串行码流变为并行传输的低速码流,增大了每个码元的周期,在传输中又使用了保护间隔来对付多径延迟,在接收端对接收序列进行适当处理后可以将多径信道等效为单径信道,并使信道对信号的影响由卷积关系变为乘积关系,从而可以有效地消除isi 。
