B_Q_Q16_AWGN
- B_Q_Q16_AWGN.rar是BPSK,QPSK,16QAM在高斯信道下的系统性能仿真，给出了信噪比SNR与误比特率BER 的关系。 16QAM是16进制的正交振幅调制在高斯信道和瑞利信道下的信噪比SNR与误比特率BER 的关系。都是matlab编写的-B_Q_Q16_AWGN.rar BPSK, QPSK, 16QAM in AWGN channel system performance simulation, given the relationship between the S
RIL
- Ril设计思想解析目前的智能机在硬件上多采用双cpu的架构，一个是基带处理器，主要处理数字信号、语音信号的编码解码以及GSM通信协议，另一个是应用处理器，运行操作系统和各种应用程序。基带处理器、射频和其它外围芯片作为一个模块，成为GSM/GPRS modem，提供AT命令接口。网络的应用已经是一个需求的热点，而目前的GSM模块大多都能支持GPRS功能。应用处理器通过AT命令集与带GPRS功能的无线通讯模块通信，为实现网络的应用提供了一个最底层的支持。-Ril intelligent design
