摘要
Abstract
The general design of a novel modem is briefly introduced,and the advantages and disadvantages of zero-IF and digital IF schemes are compared.The key issues have to be addressed in the design scheme of the digital IF modem are analyzed.The key technologies used in the design as well as their implementation methods are discussed in detail.The performance of the modem is tested,and the results indicate that the BER performance meets the design requirement,and the size and weight are reduced significantly,showing that the modem satisfies the requirement for miniaturization applications such as portable station,etc.关键词
