基于遗传算法的车间布局优化MATLAB源码(MATLAB code optimization based on genetic algorithms workshop layout)

说明：  matlab的函数目录，，作为初学者的函数字典，，很有参考价值(matlab function directory, as a function of beginners dictionary, a good reference)

说明：  运行主函数qam.m，可得到调用理论误符号率曲线和仿真结果。仿真结果包括误符号率和误码率。(running qam.m main function will receive the symbols mistakenly called theoretical curve and simulation results. Simulation results include misuse of the symbol rate and bit error rate.)

The overall objective for LTE is to provide an extremely high performance radio-access technology that offers full vehicular speed mobility and that can readily coexist with HSPA and earlier networks. OFDM/OFDMA technology is introduced for the LTE downlink, supporting very high data rates of up to 300Mbps while Single-Carrier FDMA (SC-FDMA) is used in the uplink with data rates of 80Mbps possible. 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
