Analysis of AItBOC Modulation Technology
摘要
Abstract
As to develop high-performance AltBOC receiver, based on 2-codes AhBOC (2-codes Alternate Binary Offset Carrier, 2-codes AltBOC)modulation model and combined with mathematical simulation, the modulation principle of standard AltBOC and constant envelope AItBOC are in-depth studied. The characteristics of sub-carrier and spectral density performance of standard AltBOC are compared with these of constant envelope AItBOC, and focus on analyzed these effect on receiver design. Based on simulated Galileo E5 signal without any interference case by look-up table, the advantage of constant envelope AItBOC modulation in satellite navigation signal modulation scheme is proved. An important theoretical basis is provide to the design approach of AltBOC receiver.关键词
