Abstract :
In the modern information transmission technology, digital communication has become an important mean. According to today´s modern communication technology, the paper studies the principle of QPSK and OQPSK, which is widely used in current communication system. It makes use of Matlab to simulate and verify the performance of QPSK/OQPSK. The results can make compensate for errors caused by the interference in hardware devices. Compared with the previous M files, it is simple in structure, quick and intuitive in operation, convenient and flexible in modification and easy-to-save function, and so on.
