利用MATLAB的伪随机序列的产生

In this simulink model , 16-QAM modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.-In this simulink model , 16-QAM modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.

这是一个用于油田电表抄表的程序；能够发送手机短信，使用SQLSERVER数据库储存数据；使用pcomm通讯控件控制无线调制解调器，调用AT指令集。正在现场运行，极有应用价值。-This is a meter used for oil field meter reading procedures capable of delivering a phone message, using a database storing data SQLSERVER PComm communications control to control the use of wireless modems, call the AT instruction set. Were at the scene running, there is a strong application value.

A good utility (sourcecode) to start to send data to a SPI memory Atmel AT45db.

OFDMA, Orthogonal Frequency Division Multiple Access is a broad band communication method. Here channel estimation is more crucial. Based on the FFT size used for OFDM transmission method that many number of channel co-efficients are to be estimated and received signals are to be equalized using this co-efficients. Various methods trying to improve the performance and fastness are proposed. As part of master thesis various methods have be studied and evaluated using the WiMAX 802.16 system.

AWGN channel. Uses a file called BPSK (containing BPSK voltage levels) and adds gaussian noise to it. The noise is generated by box muller equation. Note: BPSK file was generated from BPSK modulator source: BPSK.c
