基于OFDM的无线宽带系统仿真It contains mainly two parts, i.e. link-level simulator and system-level simulator. Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found out. The output of the link-level simulator is the BLER/BER vs. SNR mapping table, that can be used for the system-level simulation. System-level simulator focus on a multi-cell multi-user scenario. For the sake of simplicity, it takes the mapping table aquired in the link-level simulation, measure the actural SNR, and finds the corresponding error rate.

KMEANS Trains a k means cluster model.CENTRES = KMEANS(CENTRES, DATA, OPTIONS) uses the batch K-means algorithm to set the centres of a cluster model. The matrix DATA represents the data which is being clustered, with each row corresponding to a vector. The sum of squares error function is used. The point at which a local minimum is achieved is returned as CENTRES.

There are two files in the zip folder. bpsk_spread.m and jakesmodel.m Steps for simulation: 1] Run jakesmodel.m first 2] Then run bpsk_spread.m . 3] Note that during the first run bpsk_spread.m has no rayleigh fading.This is because the corresponding code has been commented 4] The resulting performance is stored in BER_awgn. 5] Now uncomment the Rayleigh Fading code in bpsk_spread.m file. 6] Same time comment BER_awgn (line 112) and uncomment BER_ray variable. 7] Run the simulation. To compare the perfromances of the receiver using DSSS plot the BER_awgn and BER_ray

This book code procedure according to the chapter arrangement, the 1st chapter of example under "1" the table of contents, the 2nd chapter of example under "2" the table of contents, to the order analogizes. Under corresponding table of contents including Java source code document and by it correspondence translation class document. The reader may use software and so on the text editor opens the Java source code document, examines this book the detailed code. 13th chapter the code defers to the project project laying aside. May directly use NetBeans to open the project document to carry on the code examination.

If your application uses MFC in a shared DLL, and your application is in a language other than the operating system s current language, you will need to copy the corresponding localized resources MFC42XXX.DLL from the Microsoft Visual C++ CD-ROM onto the system or system32 directory, and rename it to be MFCLOC.DLL. ("XXX" stands for the language abbreviation. For example, MFC42DEU.DLL contains resources translated to German.) If you don t do this, some of the UI elements of your application will remain in the language of the operating system.

This assignment requires you to complete the dynamic drawing components of the Date/Time Control Panel from the previous two programming assignments. In particular, you will be moving the map found in the "Time Zone" tab when the time zone changes and will be drawing a clock face corresponding to the time setting.

gcclib This gcc 1.40 suits for Linux kernel 0.11 - 0.95 Installtion hints ----------------- This suit contains include.taz, local.taz and this README file. You must download the bootimage and rootimage and install them first. The include.taz contains all the include files for using with gcc 1.40. The local.taz contains all the gcc tools & libs stored in two sepearted directories: /usr/local/lib /usr/local/bin You should copy the linux/ asm/ sys/ subdirectories into the include directory from the corresponding kernel source. Installation ------------ Goto the /usr directory. Untar the include.taz to the directory /usr/include. Untar the local.taz to the directory /usr/local. That s it! Example: -------- cd /usr tar zxvf include.taz tar zxvf local.taz

Description The MUSIC algorithm, proposed by Schmidt, first estimates a basis for the noise subspace and then determines the peaks the associated angles provide the DOA estimates. The MATLAB code for the MUSIC algorithm is sampled by creating an array of steering vectors corresponding to the angles in the vector angles.
