huffman
利用哈夫曼编码进行通信可以大大提高信道利用率，缩短信息传输时间，降低传输成本。但是，这要求在发送端通过一个编码系统对待传数据预先编码，在接收端将传来的数据进行译码（解码）。对于双工信道（即可以双向传输信息的信道），每端都需要一个完整的编/译码系统。试为这样的信息收发站设计一个哈夫曼编译码系统。(Using Huffman coding for communication can greatly improve channel utilization, shorten the transmission time and reduce transmission costs. However, this requires the sender to encode the transmitted data by a coding system at the transmitter and decode the data at the receiver. For duplex channels (i.e., channels capable of two-way transmission of information), each end requires a complete codec system. Try to design a Huffman coding and decoding system for such an information transceiver station.)

An Automatic Gain Controller (AGC) for speech signals embedded in additive noise requires Voice Activity Detection (VAD) to avoid noise amplification, a peak level detector for computing gain, and a gain controller for adjusting gain. This paper describes a low computational-intensive software AGC for use in handheld devices. The AGC provides options for static and dynamic noise floor estimation in a VAD module. Further, this paper describes analog and digital gain adjustment with gain curve selection to allow for distance perception during the AGC operation.
