一 本壓縮包說明： 包含兩個文件夾，一個word文檔，和本使用說明文本文檔。 其中： 文件夾 PCI9054為驅(qū)動程序的完整代碼（有注釋）以及類DOS應用程序。 文件夾 PCI9054應用程序（VC）是用VC開發(fā)的對應的應用程序，包括指示讀寫時間和顯示讀寫數(shù)據(jù)。 WORD文檔 是使用DriverWorks向?qū)沙绦蚩蚣艿倪^程 程序通過DriverWorks實現(xiàn)對PCI9054 BAR0，BAR2的數(shù)據(jù)寫入，讀出。讀寫方式是Direct IO方式。值得一提的是，采用該方式所能達到的讀寫數(shù)據(jù)速度只有幾M。另外，程序中沒有加入中斷控制等操作。這些我會在今后不斷得完善

We simulate uncoded BER of BPSK modulated data as a function of SNR -in an AWGN channel -in a Rayleigh fading channel -in an AWGN channel when direct sequence spreading is used and compare results to the theoretical ones. We assume coherent receiver and perfect synchronization.

This example program is the source code for the FT232BM Test Application from our Utilities page. It can be used to test the handshaking lines on FT232BM based RS232/RS485/RS422 designs. This program can also be used for programming the external EEPROM over USB in a manufacturing environment. The test features require the test cable shown on ST_232_245.pdf to be connected. Our D2XX direct drivers should be installed for this application. The code can be modified to fit your requirements. To download the application source code , click here. To download the test cable specification, click here.

Universal.Data.Access.Components 2.50 Universal Data Access Components (UniDAC) is a library of components that provides direct access to most popular database servers from Delphi, Delphi for .NET and, C++Builder. UniDAC can work with such servers as Oracle, Microsoft SQL Server, MySQL, Interbase, Firebird. The UniDAC library is designed to help programmers develop faster and cleaner cross-database applications. UniDAC is a complete replacement for such standard universal technology as dbExpress. UniDAC is a handy in use and efficient data access solution bringing into play many features specific to each server.

In 揚erformance of multi-carrier DS CDMA Systems?we apply a multi-carrier signaling technique to a direct-sequence CDMA system, where a data sequence multiplied by a spreading sequence modulates multiple carriers, rather than a single carrier. The receiver provides a correlator for each carrier, and the outputs of the correlators are combined with a maximal-ratio combiner. This type of signaling has the desirable properties of exhibiting a narrowband interference suppression effect, along with robustness to fading, without requiring the use of either an explicit RAKE structure or an interference suppression filter.
