Decision Feedback Differential Detection of π/4-DQPSK

Design & Simulation of DQPSK System for Digital Carrier Communication;

The Implementation of Digital Processing Module in π/4-DQPSK Radio in DSP;

This results presented in this paper is useful for the realization of the DQPSK transmitter system.

The COFDM modulation part is made up of blocks partition, COFDM symbol forming, DQPSK symbol mapping, frequency interleaving, difference modulation and COFDM modulation and so on.

实现不同帧之间的比特交织等。COFDM调制部分包括块划分及COFDM符号形成、DQPSK符号映*、频率交织、差分调制及COFDM调制等环节。
