A sampling method based on the modified autocorrelation receiver is proposed for FG-MSDD, which has a trellis structure. The trellis can be decomposed into multiple subtrellises depending on the FG factorization. Then, a methodology for APPs is derived when the forward-and-backward message passing is performed on the subtrellises. The main advantage of FG-MSDD is that it exploits soft information accurately with the aid of the bidirectional message passing. In addition, the proposed FG-MSDD, in conjunction with any soft-input soft-output (SISO) decoding scheme, is capable of obtaining an iterative detection algorithm. Various performance evaluation results obtained by means of computer simulations have verified that the proposed algorithm improves detection performance for the noncoherent UWB TWRS.]]> Tue, 29 Aug 2017 11:58:45 GMT https://trid.trb.org/View/1471800 Development of a Platform to Enable Real time, Non-Disruptive Testing and Early Fault Detection of Critical High Voltage Transformers and Switchgears in High Speed Rail https://trid.trb.org/View/1475693 Sun, 23 Jul 2017 19:55:44 GMT https://trid.trb.org/View/1475693 Signal Processing for Fast RC Bridge Slab Damage Detection by Using UHF-band Radar https://trid.trb.org/View/1466641 Sun, 04 Jun 2017 18:02:25 GMT https://trid.trb.org/View/1466641 A Novel Passive Wireless Sensor for Concrete Humidity Monitoring https://trid.trb.org/View/1424460 Tue, 25 Oct 2016 09:50:50 GMT https://trid.trb.org/View/1424460 Identification of Postal Mails and Crates by New Developed UHF RFID Antenna https://trid.trb.org/View/1424511 Tue, 25 Oct 2016 09:50:32 GMT https://trid.trb.org/View/1424511 Research of Readability and Identification of the Items in the Postal and Logistics Environment https://trid.trb.org/View/1422265 Tue, 27 Sep 2016 16:19:02 GMT https://trid.trb.org/View/1422265
