中文说明:应用背景这段代码,你能够产生BPSK不规则的正交振幅或相位星座。从一个通用的模板是容易和灵活的添加一个案例来开发新的星座功能。你可以发射改变符号的数量,滚降系数,比特率,采样频率,等& nbsp;在接收机可以测量体或EVM评估发射机/接收机的性能。还可以添加信噪比来评价星座输出中噪声的影响。关键技术在MATLAB中我实现了一个函数来生成典型的任意线性调制星座性能评价。代码清晰,灵活的允许和评价等问题的频率和相位偏移,时序变化offsete,滚降的影响,信噪比的影响,EVM和MER的影响,在别人。只是用tx_line和rx_line和配置参数来测试你的模拟。
English Description:
Application background With this code you can be able to generate from bpsk to irregular amplitude quadrature or phase constellations. From a generic template is easy and flexible to add a case to develop new constellation functions. You can transmitt changing the number of symbols, roll off factor, bit rate, frequency sampling, etc. At the receiver you can measure the MER or EVM and evaluate the performance of the transmitter/receiver. You can also add SNR to evaluate the impact of noise in constellation output. Key Technology In matlab i implemented a function to generate typical and arbitrary constellations for linear modulation performance evaluation. The code is legible, and flexible to allow changes and evalueate impairments such as frequency and phase offset, timing offsete, roll off impact, SNR impact, EVM and MER impact, within others. Just use Tx_line and Rx_line and configu
