Abstract

This paper discusses the despread of low signal to noise ratio of the direct sequence （DS）spread spectrum signals using intermediate-frequency recirculation summation loop （IFRSL）.Fundamental principles of IFRSL and some problems in the loop design are described.Finally

experimental results are shown for signals through the satellite channel.
