设计了一个OFDM接收机，并采用1fI公司的TMS320C6416芯片进行实现。在假设理想

同步的前提下，该系统进行了FFT变化、使用了Ls(最小二乘法)进行信道估计，并且采用了

QPSK算法进行解调。最后将接收机输出数据与发端数据进行比较，在不同信噪比情况下计算其

误码率，得出了比较理想的结果。-An OFDM receiver is designed in山is paper and realized on the platform of the 1MS32OC6416 chip

of the TI company．Under the assumption of ideal synchronization．n叩transformation is realized in the system

wit}l LS method implemented in the channel estimation module and QPSK used in the demodulation module．

Finally，BER is calculated in different cases of SNR and the result is achieved as expected．
