In this paper, we present optimal network coding which can maximize achievable rate region in two-way relaying discrete channels, where there are two communicating nodes and one relaying node. We focus on a low-complexity relaying protocol termed the detect-and-forward (DtF) scheme, in which the relaying node does not require channel decoding but detection. We first analyze the achievable rate region...
We investigate modulation schemes optimized for two-way wireless relaying systems, for which network coding is employed at the physical layer. We consider network coding based on denoise-and-forward (DNF) protocol, which consists of two stages: multiple access (MA) stage, where two terminals transmit simultaneously towards a relay, and broadcast (BC) stage, where the relay transmits towards the both...
We investigate on the design of modulation schemes suited for two-way wireless relaying systems that apply network coding at the physical layer. We consider network coding based on denoise-and-forward (DNF), which consists of two stages: multiple access (MA) stage and broadcast (BC) stage. For the case of QPSK constellation in the MA stage, we introduce the modulation-related problems in DNF. We propose...
In this paper, we propose a low-complexity equalizer whose performance approaches that of the optimum maximum-likelihood (ML) estimator, in ultra-wideband (UWB) multiple- input multiple-output (MIMO) channels. Although the ML estimation offers the excellent performance, it is generally of high complexity due to the large size of searching space. Through a theoretical search-space analysis, we reveal...
