Title: | Software parallel implementation of a DS-CDMA multiuser detector |

Abstract: | In this article the complexity and runtime performance of two Multiuser Detectors for Direct Sequence-Code Division Multiple Access were evaluated in two hardware platforms in order of a possible deployment in base stations. The detectors are based on the Frequency Shift Canceller concatenated with a Parallel Interference Canceller. This detector is very scalable which shadows the complexity penalty of a serial implementation in which other detectors have advantage. Implementations for the Time Division-Code Division Multiple Access deployed in China, in two software platforms one in OpenMP and other in CUDA were done. It is demonstrated that a realtime implementation is possible with a General Propose Graphics Processor Unit. This is part of a broader project aiming to take advantage of present parallel hardware to bring improved Multiuser technology to the present and future Base Stations, mainly in Universal Mobile Telecommunications System-Time Division Duplex. |
