代码说明:

  Matlab编程实现FFT变换及频谱分析的程序代码(适合初学者加强理解)。(1)用Matlab产生正弦波,矩形波,以及白噪声信号,并显示各自时域波形图;(2)进行FFT变换,显示各自频谱图,其中采样率,频率、数据长度自选;(3)做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱;(4)用IFFT傅立叶反变换恢复信号,并显示恢复的正弦信号时域波形图。(Matlab codes for FFT Understanding which contains sine wave,rectangular wave and the reletaed frequency spectrum figure about MSE,Log,IFFT and so on.)

    Additionally, LTE supports operation both in paired and unpaired spectrum (FDD and TDD) using channel bandwidths of approximately 1.4MHz up to 20MHz. The frequency domain scheduling can be done in OFDMA. One of the main challenges in OFDMA is the high peak-to-average radio of the transmitted signal, which requires linearity in the transmitter. The linear amplifiers have low efficiency therefore, OFDMA is not an optimized solution for a mobile uplink where the
