This packet is a IS-95 baseband simulation for 1 data channel of 9.6 KBps rate.
The simulation is written for static channel and AWGN noise. The packet include:
1) Packet Builder (Viterbi Encoding, Interleaver, PN generation)
2) Modulator (RRC filter)
3) Demodulator (Matched Filter, RAKE receiver ...
Linux/Unix编程 The UCL common multimedia library implements a number of algorithms and protocols needed by a number
The UCL common multimedia library implements a number of algorithms and protocols needed by a number of our applications. It compiles standalone on a range of Unix systems (Solaris, Linux, Irix, FreeBSD, MacOSX) and on Windows 95/98/NT/XP. The following protocols/algorithms are included in the libra ...
压缩解压 赫夫曼编译码器: 用哈夫曼编码进行通信可以大大提高信道利用率
赫夫曼编译码器:
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(复原)。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写一个哈夫曼码的编 ...

主題 :
Low power Modified Booth Multiplier
介紹 : 為了節省乘法器面積、加快速度等等,許多文獻根據乘法器中架構提出改進的方式,而其中在1951年,A. D. Booth教授提出了一種名為radix-2 Booth演算法,演算法原理是在LSB前一個位元補上“0”,再由LSB至MSB以每兩個位元為一個Group,而下一個Group的LSB會與上一個Group ...
