Altera FFT IP核 输出为0问题

<p>求助高人指点，我仿真OFDM通信系统，调用FFTT IP核进行IFFT运算，输出数据实部和虚部为0，exp为不定态。</p>

<p>Altera FFT IP配置：<br />
Transform<br />
&nbsp; Length:64<br />
&nbsp; Direction:Bit-directional<br />
&nbsp;&nbsp;<br />
I/O<br />
&nbsp; Data Flow:Streaming<br />
&nbsp; Input Order:Natural<br />
&nbsp; Output Order:Natural<br />
&nbsp;&nbsp;<br />
Data and Twiddle<br />
&nbsp; Representation:Block Floating Ponit<br />
&nbsp; Data Input Width:16<br />
&nbsp; Twiddle Width:16<br />
&nbsp; Data Output Width:16<br />
Latency Estimates<br />
Calculation Latency:64<br />
Throughput Latency:64</p>
