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開發的對應的應用程序，包括指示讀寫時間和顯示讀寫數據。 WORD文檔 是使用DriverWorks向導生成程序框架的過程 程序通過DriverWorks實現對PCI9054 BAR0，BAR2的數據寫入，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據速度只有幾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.

SPREAD SPECTRUM MODULATION TECHNIQUES -spread spectrum - those modulation methods that are producing a signal whose spectrum is more wider than of the data signal, the occupied frequency band being independent by the signal of data band. -The signals with spread spectrum of direct sequence type BPSK (BPSK-DS-SS) -The signals with spread spectrum of direct sequence type QPSK – DS–SS - Frequency hopping spread spectrum signals (FH-SS)

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.
