Abstract
The performance of a fractionally spaced decision feedback equalizer (DFE) for spread-spectrum multiple access (SSMA) systems, which does not make explicit use of the interferers' spreading sequences, is evaluated. It is found that the system performance is acceptable even for small spreading gains in a slow-fading multipath environment. Good performance has been achieved without the knowledge of the desired user's spreading sequence. This could lead to less complex receivers and higher capacity of users for SSMA than that of other access techniques.Keywords
