LTE中PDSCH的链路级仿真过程源代码分析，包括信道编码，预编码，OFDM调制(LTE PDSCH link level simulation in the process of source code analysis, including channel coding, precoding, OFDM modulation)

这个函数返回n点2dw波段的傅里叶变换的DFT样本序列。通常情况下，以插值点的方式进行放大。(This function returns N point DFT samples of 2dw band of Fourier transform of a sequence. Typically, fft() returns N samples of Fourier transform ranging from 0 to 2pi. This function takes the N-point DFT samples and returns N-point samples corresponding to frequency band wc-dw to wc+dw.)
