  1. 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的基本原理是將高速串列碼流變為并行傳輸的低速碼流,增大了每個碼元的周期,在傳輸中又使用了保護間隔來對付多徑延遲,在接收端對接收序列進行適當處理后可以將多徑通道等效為單徑通道,並使通道對信號的影響由卷積關系變為乘積關系,從而可以有效地消除isi 。
