A Low-Complexity Joint Synchronization and Detection Algorithm for Single-Band DS-CDMA UWB Communications |
|
| Abstract | The problem of asynchronous direct-sequence code division multiple access (DS-CDMA) detection over the ultra-wideband (UWB) multipath channel is considered. A joint synchronization, channel-estimation and multi-user detection scheme based on the adaptive linear minimum mean-square error (LMMSE) receiver is presented and evaluated. The receiver is based on [3] extended with a synchronization method from [6]. Further, a novel non-recursive least-squares algorithm capable of reducing the complexity of the adaptation in the receiver while preserving the advantages of the recursive least-squares (RLS) algorithm is presented. |
