A framework is proposed that allows for a joint description and optimization of both binary polar coding and 2^m-ary digital pulse-amplitude modulation (PAM) schemes. For the latter, the multilevel coding (MLC) approach as well as bit-interleaved coded modulation (BICM) are considered. The conceptual equivalence of polar coding and multilevel coding is covered in detail. Based on an alternative characterization...
The paper considers bit-interleaved coded modulation with on-off signaling constellations based on the IEEE 802.15.6 Standard for future body area networks (BANs) with a wideband PHY. The transmitter of BANs is constrained by the IEEE 802.15.6 Standard to have a conventional BCH(63,51) encoder and finite interleaving. The paper presents a proposal of a simple receiver architecture targeting low power...
We address the problem of constructing practical coding schemes for Integer-Forcing (IF) equalization. Previously proposed IF schemes suggested the use of nested lattice codes or linear block codes over Zq. While such codes have good properties from a theoretic point of view, their implementation complexity may become significant when q is large. In this work we show that at high transmission rates,...
The block fading channel model is very useful for many systems in urban environments. When striving for high performance implying high rate, full-diversity and excellent coding gain, coded modulations have to be used. When linear precoding is used, error-correcting codes can focus on achieving a high coding gain and are not constrained in coding rate so that no bandwidth is sacrificed. However, optimal...
Bit-interleaved coded modulation with iterative decoding (BICM-ED), which can improve the BER performance within limited bandwidth, is getting extensive international attention. Symbol mapping, defined by the signal constellation and the bit labeling is the crucial design parameter to achieve a high coding gain for BICM-ED. In almost all the existing work, when the performance of various symbol mappings...
In this paper, we study the design of constellation labeling for iteratively decoded concatenated multilayer space-time error correcting codes (STECCs). We propose also an iterative receiver structure exploiting the inter-dependence between labeling bits addressing one modulation symbol. Simulations using quadratic amplitude modulation of order four (4-QAM) with two constellation labelings show the...
This paper focuses on the applicability of bit-interleaved space-time coded modulation with iterative decoding (BI-STCM-ID) to wireless local area networks (WLAN). A new intuitive space-time diversity scheme, which ensures a low error rate for small signal-to-noise ratios (SNR) and good asymptotic performance, is provided. The presented technique can ensure compatibility with todaypsilas WLAN specifications...
It is shown both theoretically and experimentally that 8B/10B encoding is an efficient technique to mitigate the inherent modulation crosstalk in optical labeling scheme using orthogonal modulation.
