OFDM 传输的一种新的组合脉冲噪声缓解方案研究
摘要-Impulsive噪音缓解了正交频分复用(OFDM)可以使用两个阈值剪贴归零方案来完成。我们引入一个新的结合脉冲噪声消除方法,称为clippingreplacement-归零计划,其中有三个考虑阈值:限幅阈Tclip,更换门槛TREP和归零门槛Tnull。当接收到的OFDM样本的幅度高于TREP和下方Tnull我们将其设置为所述平均幅度JX?无噪声的OFDM样本第j。模拟结果表明,附加的动作,替换动作,与TREP的一个很好的选择带来在误码率的降低。

主要为工控设计的,先配置好硬件所需的文件,和需要发送的命令,配合tftp,就可以自动下载硬件所需要的系统文件了。还可以自动发送命令给硬件。类似超级终端。仅共学习参考。-Designed primarily for industrial control, first configured hardware required documents, and the need to send orders, with tftp, you can automatically download the hardware needed for the system files. Can also automatically send a command to the hardware. Similar to HyperTerminal. Only a total learning reference.

This packet is a IS
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)
4) Receiver (HD or SD) (Deinterleaver, Viterbi Decoder).
You should run "Simulation.m" function that include all modules.

利用哈夫曼编码进行通信可以大大提高通信信道利用率,缩短信息传输时间,降低传输成本。这要求在发送端通过一个编码系统将传输数据预先编码;在接收端将传来的数据进行译码(复原)。对于双工信道(即可以双工传输信息的信道),每端都需要一个完整的编/译码系统。为这样的信息收发站设计的一个哈夫曼编/译码系统。 (2-use Huffman coding communication can greatly enhance communication channel utilization, reduced transmission time, and lower transmission costs. This requires the transmitter through a coding system will transmit data in advance coding; The receiving end of the data came decoding (recovery). For dual-channel (that is, information can duplex transmission channel), each side needs a complete encoding/decoding system. For this information hubs designed a Huffman encoding/decoding system.
