Abstract :
This paper describes the influence of multiple access (MA) interference on the performance of a non-coherent hybrid direct sequence fast frequency hopping SSMA communication system applying FSK-modulation. The MA-interference plays an important role in determining the total interference in a spread spectrum system, especially in a non-cellular environment, where power control is hardly possible. A cross correlation factor which is directly responsible for this interference is derived. Using this factor, a comparison between slow and fast frequency hopping (both in combination with direct sequence) is made. At the end two sets of Kasami codes are selected which offer a good performance
