The QPSK Modulation and FEC Error Correction in DVB Receiver System
QPSK调制与FEC差错控制在DVB系统中的应用

Abstract Based on a brief discussion of the basic structure of the DVB receiver,this paper analyses the variable rate QPSK demodulation and FEC error correction in the digital satellite receiver and compares two types of integrated circuit chips applied in the DVB receiver made by ourselves.
