采用直接法实现实信号输出信道化发射机matlab仿真程序:可清楚地看出输入的基带信号被分别调制到了相应的频带上，并且输入的各路基带信号的频谱结构可以很明显地在输出的频谱中体现出来-Using the direct method to achieve real signal output channel of the transmitter matlab simulation program: You can clearly see that the input base-band signal is modulated separately to the corresponding frequency band, and the input signal spectrum with the roadbed structure can be clearly in the output reflected in the spectrum

RFM12B and AVR The RFM12B tranceiver module has become quite popular recently due to its low price comparing to other modules on the market. But many people nd it hard to make these tranceivers work (mainly because of buggy programming guide provided by manufacturer, I guess...). This short article contains compact and simple code that can be used just to get these modules running for the rst time. It is based on manufacturer s examle code with slight (but crucial) changes.
