QPSK调制Modem的C实现及文档说明

This is a readme file for using(running) the DQPSK modem simulation.

1. To compile the simulation program, you will need a Borland C++ 5.0 compiler or
   an equivalent C++ compiler.
2. The main program is in the file "DQPSKmodem.cpp", so make sure you build this
   file ONLY!!!
2. Before running the simulation program, you will need to create an
   input file("InputParameters.txt") for the program first. 
3. To modify the parameters to the program, open this input file and modify it
   accordingly.
4. Go to DOS-prompt and type the executable program name to start the program.

5. You might also need to look at the "backgrounds.doc" for some background 
   theories which might help you to understand the program
6. If you have any problems on running the program, feel free to send me 
   an e-mail:    4cl2@qlink
