此OFDM系統檔是TX+RX的版本，也可以正常傳輸。但當我們按下開始執行時，TX與RX會同時作用，卻疑似因為訊號時間沒有同步的問題導致BER非常的糟糕，想請各位幫我看一下程式該如何修改以解決這個問題。
在下感激不盡!!
This OFDM file is including TX & RX, and it can be used normally. But when we start to transmit (TX and RX would start at the same time), the signal is out of synchronized, so that I got really BAD performance of BER. Please kindly help me to solve this problem.by modifying this program.
Thanks & Best Regards
