A Simplified Direct-Sequence Spread Spectrum (DSSS) Multi-User Interference Variance Estimator

Fourth IEEE Workshop on Sensor Array and Multichannel Processing, 2006., 2006
In the literature many approaches have been reported for calculation of the multi-user interference variance in a direct-sequence spread spectrum (DSSS) system. These approaches are very complicated. In this paper a simplified approach for calculation of the DSSS multi-user interference variance is presented.

A efficient channel utilization to increase in the number of users in multi-user direct-sequence spread spectrum (DSSS) systems

2010 International Waveform Diversity and Design Conference, 2010
When the number of these DSSS radios is increased, capacity of the existing wireless system has become an issue. In this paper, a novel approach is presented that provides an efficient channel utilization for a significant increase in the number of DSSS radios for a given channel.
