无线通信类的，适用于自适应调制算法，用户算法(AMC algorithm)

该程序用matlab仿真了OFDM下行链路的资源分配，包括功率和比特分配、子载波分配(The program matlab simulation the OFDM downside link distribution of resources, including power and bit allocation, the subcarrier allocation )

对不同调频周期数 不同时间带宽积和不同调 频 极 性 等 多 种 组 合 情况下的 信号正交性进行了分析 发现通过不同调制参数的灵活组合可以实现 信号正交调制 (Analysis found that is orthogonal to the signal in the case of the variety of combinations of different FM number of cycles of the different time-bandwidth product and different FM polarity signal quadrature modulation can be achieved by the flexible combination of different modulation parameters)

说明：  阐述了RS-485总线规范，描述了影响RS-485总线通信速率和通信可靠性的三个因素，同时提出 了相应的解决方法并讨论了总线负载能力和传输距离之间的具体关系。 (Described the RS-485 bus specification, describes the impact of RS-485 bus communication speed and communication reliability of the three factors, while the corresponding solutions presented and discussed the bus load capacity and the specific relationship between the transmission distance.)
