其原理很简单,就是MSP430F14x系列单片机Timer A模块有一个比较/匹配功能,利用这一功能可以输出任意频率、任意占空比的方波,把这些方波输给蜂鸣器就可以播放了。当然要让蜂鸣器播放《最炫民族风》,最大的挑战是写C语言版的“乐谱”。所幸小时候学过五六年的小提琴,再加上物理竞赛的背景,因而对于乐谱、乐理、音频、节奏等等关键概念都略懂一二。废话不多说了,直接上源代码:
(The principle is very simple, is MSP430F14x Series MCU Timer A module has a compare/match function, the use of this feature can be output at any frequency, arbitrary duty cycle square wave, square wave lost these can play a buzzer. Of course, to make the buzzer play " the most unusual national wind" , the biggest challenge is to write C-language version of " music." Fortunately, the child learned the violin in 2056, coupled with the physical contest background, and thus for sheet music, music theory, audio, rhythm, etc. have little knowledge of twelve key concepts. Ado, directly on the source code:)

MRC、LMMSE接收端检测仿真程序,IA干扰对齐的链路级仿真
包含IA、MRC/LMMSE/ZF接收端的示例程序
最大比最大比合并是所有合并方式中最佳的,在最大比合并时,分集支路中每条的电压信号是相同的,因而相干电压相加,同时每条支路的信号电压各自加权达到最佳。
LMMSE线性最小均方误差检测算法是一种线性检测算法。
传统ZF算法针对用户为单天线,基站为多天线的场景,ZF算法要求用户的信号加权向量与其他用户的信道向量满足正交的关系,
