A Low-Complexity Joint Synchronization and Detection Algorithm for Single-Band DS-CDMA UWB Communications

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 multiuser detection scheme based on the adaptive linear minimum mean square error (LMMSE) receiver is presented and evaluated. Further, a novel nonrecursive least-squares algorithm capable of...

Iterative Multiuser Detection for DS-CDMA/MC-CDMA Powerline Communications

The increasing ubiquity of the Internet is creating a rapidly growing demand for larger bandwidth to the home. Currently the narrowband twisted-pair access network from an optical network unit (ONU) or a central office (CO) to a customer’s premises, the socalled “last dirty mile”, is the bottleneck for Internet traffic. The increasing demand for a home/office network further necessitates a flex...

Low Complexity Joint Iterative Equalization and Multiuser Detection in Dispersive DS-CDMA Channels

Communications in dispersive direct-sequence code-division multiple-access channels suffer from intersymbol and multiple-access interference, which can significantly impair performance. Joint maximum a posteriori probability equalization and multiuser detection with error control decoding can be used to mitigate this interference and to achieve the optimal bit error rate. Unfortunately, such op...

Multiuser detection for DS-CDMA UWB in the home environment

We demonstrate the effectiveness of multiuser detection for an ultra-wideband (UWB) pulse based direct sequence spread spectrum system using code division multiple access. Extensive simulations were run using channel soundings of the 2–8 GHz band collected in a residential setting and characterized by a high level of multipath fragmentation. We show that the adaptive minimum mean square error (...

Low Complexity Asynchronous Ds-cdma Detectors

In this paper near-far resistant multiuser-detectors for an asynchronous direct-sequence code-division multiple access (DS-CDMA) system, which do not need the code-matched lter outputs from all users are presented. The DS-CDMA system under consideration is a multiuser system using BPSK modulation. The system operates over an additive white Gaussian noise channel with unknown propagation delays....
