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

Matlab的M文件编写的数控插补2D直线算法仿真。具体参数可使用：X-500,Y-600，Fc-600，Fs-0，Fa-0，at--200.仿真的本意是为了验证DSP上同类插补算法的正确性(Matlab M-file to prepare the CNC interpolation algorithm for 2D simulation of a straight line. Specific parameters can be used: X-500, Y-600, Fc-600, Fs-0, Fa-0, at- 200. The simulation is intended to verify the DSP on the correctness of the same interpolation algorithm)
