Lossless Data Compression Toolkit Version 1.1 of the lossless data compression toolkit by Nico deVries. The C sources in this toolkit include an LZW compressor, AR002 archiver, a PPM like compressor using arithmetic compression, Huffman compressor, splay tree program, and LZRW1. Quite a variety.
单片机开发 红外通信是利用950nm近红外波段的红外线作为传递信息的媒体
红外通信是利用950nm近红外波段的红外线作为传递信息的媒体，即通信信道。发送端采用脉时调制（PPM）方式，将二进制数字信号调制成某一频率的脉冲序列，并驱动红外发射管以光脉冲的形式发送出去；接收端将接收到的光脉转换成电信号，再经过放大、滤波等处理后送给解调电路进行解调，还原为二进制数字信号后输出。 ...

Noncoherent receivers are attractive for pulsed UWB systems due to the implementation simplicity. To alleviate the noise effect in detecting UWB PPM signals, this letter proposes a simple yet flexible weighted noncoherent receiver structure, which adopts a square-law integrator multiplied with a win ...
