Zhao Jian · Jisuanji gongcheng · 2012
Dual Carrier Modulation(DCM) technology is chosen as the higher data rate modulation technology in Wireless USB system.Different demodulation methods for the DCM are presented,including soft bit,Maximum Likely(ML) soft bit and Log Likelihood Ratio(LLR).Frequency diversity and Channel State Information(CSI) are further technologies to enhance the system decoding.Experimental results show that using LLR demodulation methods with frequency diversity and CSI decoding technologies can maximize system transmission performance.
