MIMO自动球形检测算法
- 该算法利用统计裁减有效减小了自动球形译码(ASD)算法 中边界节点列表的大小 s,并可通过对参数的适当设置获得误符号率性能与复杂度之间的折衷。分析与仿真表明, 当采用较高电平调制(电平数大于 4)时,在相同信噪比范围内,PASD 在几乎不损失误符号率性能的前提下, 较 ASD 节省大于 30%的比较次数。

- 本设计的指导思想是利用红外发光管发射红外线,红外接收管接收此红外线,并将其放大、整流形成高电平信号.当有人或物挡住红外光时,接收管没有接收到红外信号,放大器将输出低电平,同时将这个电平信号送入单片机进行控制计数,并经译码驱动电路使数码管显示数值。这样就得到要统计的人或物的数量。-The design of the guiding idea is to use infrared emission infrared LED and infrared receiver to receive the i

- 该电路由一片四双向模拟开关集成电路CD4066为核心构成。每个电路内部有四个独立的能控制数字或模拟信号传送的开关。当水箱无水时,由于180K电阻的作用,使四个开关的控制端为低电平,开关断开,LED 不发光。随着水位的增加, 由于水的导电特性,使得IC的13脚为高电平,S1接通,LED1点亮。当水位逐渐增加时,LED依次发光指示水位。水满时, LED4发光, 显示水满。同时T1导通, B发出报警声,提示水已满。不需要报警声时,断开开关K即可。 -The circuit consists of a
