scr ipt for simulating QPSK(4-QAM) transmission and reception and compare the simulated and heoretical symbol error probability

一篇有关推导多进制相位调制在高斯信道条件下的符号错误概率，具有重要的参考意义-A derivation of M-ary phase modulation on the Gaussian channel symbol error probability under the condition has important reference value

。研究了瑞利衰落信道下两跳放大前传协作中继系统的最优化功率分配问题。推导了高信噪比条件下的协作中继系统的中断概率的理论公式. 协作中继 放大前传 最优化功率分配 误符号率 中断概率-Optimal power allocation for two hops amplify- and- forward cooperative relaying communication systems in Rayleigh fading channel was studied. cooperative

In this paper, we first propose an optimum relay ordering algorithm for the multi-branch multi-hop cooperative diversity networks. This optimum algorithm has a high complexity that makes it hard to implement. Therefore, a suboptimum relay ordering al

这是一份关于MIMO无线系统设计的一份分析资料，另外在最后还附带了程序。很不错的！-In this report, we will be mostly talking about QAM. So for completeness, in Fig. 2, we plot MATLAB simulation results for the probability of symbol error of 16-QAM. As it can be seen, the performance deg
