Realization of π/4-DQPSK Modulation and Demodulation in Digital Video Wireless Transmission By DSP

研究数字图像无线传输中基带信号处理的关键技术 ,根据DSP的特点优化π/ 4 -DQPSK调制、解调的算法 ,对基带差分解调进行计算机仿真 ,并提出用DSP芯片实现π/ 4

Some key base-band processing(BBP) techniques in digital video wireless transmission are researched. Based on the characteristic of DSP, the algorithms of π/4-DQPSK modulation and demodulation are optimized as well. The differential demodulation of base-band is simulated and hardware solution by DSP chip for π/4-DQPSK modulation and demodulation is implemented.
