Abstract :
In this paper we propose and investigate a frequency domain approach to channel estimation, and detection for ultra wide band (UWB) direct sequence code division multiple access (DS-CDMA) systems. The channel estimation and detection approach is single user based, and operates in the frequency domain. In the presence of multiple access interference (MAI) the algorithm is appropriately modified to include the capability of canceling the interference through the exploitation of its frequency domain correlation.
