Cooperative Signaling with Soft Information Combining (2010)
We propose a Decode-and-Forward (DF) scheme using distributed Turbo code (DTC) for a three-node (source, relay, and destination) wireless cooperative communication system. The relay decodes, then interleaves, and reencodes the decoded data. It then forwards the reencoded packet and its instantaneous receive SNR to the destination. The performances using both ideal and quantized SNR are studied. The destination uses a modified metric within a Turbo decoding algorithm to scale the soft information calculated for the relay code. The proposed scheme is simple to implement and performs well.

Xu, R.; Morris, K.A.; Woodward, G.K.; Kocak, T. (University of Canterbury. Electrical and Computer Engineering, 2012)Sequential decoding can achieve a very low computational complexity and short decoding delay when the signal- to-noise ratio (SNR) is relatively high. In this paper, a low-complexity high-throughput decoding architecture ...
Retransmission Strategies for Cyclic Polling over Wireless Channels in the Presence of Interference Gamba, G.; Tramarin, F.; Willig, A. (University of Canterbury. Computer Science and Software Engineering, 2010)In this paper we consider retransmission strategies for centralized cyclic polling-based systems over wireless channels subject to external interference. The considered strategies differ in the time when retransmissions ...
