The introduction of Vehicle-to-X (V2X) communication enhances the perception range of a vehicle significantly. The technology, however, is subjected to the network effect: a minimum number of communication partners need to be within range, in order for V2X applications to work. Taking current vehicle replacement rates on the market into account, the time of market introduction is critical, as early...
In current and future wireless standards, such as WiMAX, 3GPP-LTE or LTE-Advanced, receiver terminals have to support numerous operating modes for each protocol [1], as well as sophisticated transmission techniques, especially enhanced MIMO detection and iterative forward error correction (FEC). MIMO detection and FEC belong to the most computationally complex parts of the receiver-side baseband signal...
High detection complexity is known to be one of the major challenges in MIMO communications based on spatial multiplexing. Tuple Search Detector (TSD) was recently introduced, significantly reducing detection complexity in comparison to conventional algorithms while achieving close to full max-log-APP BER performance. Irregular control flow and sequential nature of depth-first-based detectors frustrate...

Nowadays, high detection complexity is known to be one of the major challenges in MIMO communications based on spatial multiplexing. Tuple search (TS) sphere detection was recently introduced, demonstrating to represent a promising approach in this context. It provides significant complexity reduction in comparison to conventional algorithms, providing in addition close to full max-log-APP BER performance...
Soft-In Soft-Out (SISO) MIMO detection algorithms providing soft information to subsequent channel decoder are computationally high complex. Realizations based on depth-first search e.g. the Tuple Search (TS) algorithm enables near full MaxLogAPP optimal detection at much reduced but still high complexity. This paper presents a novel method for the complexity reduction of SISO MIMO detection algorithms...
