论文摘要
在本文中，我们为IIR频道提出了一个新的OFDM系统，其形式为$ b（z）/a（z）$，用于两个多项式$ a（z）$和$ b（z）$。与FIR通道上的常规OFDM变速箱不同，添加了OFDM符号的护罩间隔，以使接收器的相应零件是接收到的OFDM符号的循环前缀（CP）。后卫间隔和CP长度相同，不小于多项式$ a（z）$和$ b（z）$的订单。没有防护间隔的OFDM符号与没有CP的常规OFDM符号相同。在接收器，然后将IIR频道转换为$ n $ InterSymbol干扰（ISI）免费子通道，其中$ n $是OFDM符号的子载体数量。
In this paper, we propose a new OFDM system for an IIR channel with the form of $B(z)/A(z)$ for two polynomials $A(z)$ and $B(z)$. Different from the conventional OFDM transmission over an FIR channel, a guard interval of an OFDM symbol is added such that the corresponding part at receiver is the cyclic prefix (CP) of the received OFDM symbol. The guard interval and CP lengths are the same and not smaller than the orders of polynomials $A(z)$ and $B(z)$. The OFDM symbol without the guard interval is the same as the conventional OFDM symbol without the CP. At the receiver, the IIR channel is then converted to $N$ intersymbol interference (ISI) free subchannels, where $N$ is the number of subcarriers of an OFDM symbol.
