红外报警器的c代码。 基于清翔电子的c51单片机最小开发板开发，代码带有注释。如果不布置外围红外电路，IO口检测到低电平触发蜂鸣器报警。必须有液晶1602才能正常运行程序，不然需要注释掉LCD相关代码。(Infrared alarm c code. Based on Qingxiang electronic C51 microcontroller development board, the code with notes. If the peripheral infrared circuit is not arranged, the low level trigger buzzer alarm is detected at the IO port. There must be liquid crystal 1602 to run the program normally, otherwise you need to annotate the LCD related code.)

说明：  OFDM即正交频分复用技术，多载波调制的一种。其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。。每个子信道上的信号带宽小于信道的相关带宽，因此每个子信道上的可以看成平坦性衰落，从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分，信道均衡变得相对容易。(Orthogonal Frequency Division Multiplexing (OFDM) is a kind of multi-carrier modulation. The main idea is to divide the channel into several orthogonal sub-channels, convert high-speed data signals into parallel low-speed sub-data streams, and modulate them to transmit on each sub-channel. The signal bandwidth on each sub-channel is less than the correlation bandwidth of the channel, so it can be seen as flat fading on each sub-channel, which can eliminate inter-symbol interference. Moreover, since the bandwidth of each subchannel is only a small part of the original channel bandwidth, channel equalization becomes relatively easy.)
