Description: The use of hardware description languages (HDLs) is becoming
increasingly common for designing and verifying FPGA designs.
Behavior level description not only increases design productivity, but also
provides unique advantages for design verification. The most dominant
HDLs today are Verilog and VHDL. This application note illustrates the
use of Verilog in the design and verification of a digital UART (Universal
Asynchronous Receiver & Transmitter).

Description: 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.
