Publication number: 20110128994Abstract: A novel ultra-wide bandwidth receiver structure dubbed the “zonal” receiver is proposed to detect time-hopping ultra-wide bandwidth signals in multiple access interference channels. The zonal receiver outperforms the conventional matched filter ultra-wide bandwidth receiver and the recently proposed soft-limiting ultra-wide bandwidth receiver when only MAI is present, or AWGN is negligible compared to MAI. In more practical mixed MAI-plus-AWGN environments, the zonal ultra-wide bandwidth receiver achieves better performance than the conventional matched filter ultra-wide bandwidth receiver, the recently proposed soft-limiting ultra-wide bandwidth receiver, and the recently proposed adaptive threshold soft-limiting ultra-wide bandwidth receiver. In multipath fading UWB channels, a new Rake receiver based on the zonal UWB receiver design has been proposed, this new Rake receiver can achieve better BER performance than the conventional matched filter based Rake receiver.Type: ApplicationFiled: March 7, 2008Publication date: June 2, 2011Applicant: THE GOVERNORS OF THE UNIVERSITY OF ALBERTAInventors: Norman C.

Publication number: 20110041032Abstract: Two hybrid message decoders for low-density parity-check (LDPC) codes are proposed. One decoder uses a posteriori probability ratio (APPR) and a posteriori probability difference (APPD), and the other decoder uses a logarithm a posteriori probability ratio (LAPPR) and a logarithm a posteriori probability difference (LAPPD) as hybrid message. Since the variable node and check node processing can be readily done using APPR and APPD, respectively, the proposed decoders have lower complexity than the conventional decoder that uses LAPPR only as a message.Type: ApplicationFiled: August 19, 2008Publication date: February 17, 2011Applicant: THE GOVERNORS OF THE UNIVERSITY OF ALBERTAInventors: Young Gil Kim, Norman C.
