Lattice Decoding for Joint
نویسنده
چکیده
A new joint detection method based on sphere packing lattice decoding is presented. The algorithm is suitable for both synchronous and asynchronous multiple access CDMA-DSSS systems, and it may jointly detect up to 32 users with a reasonable complexity. The detection complexity is independent of the modulation size and large M-PAM or M-QAM constellations can be used. Further, a theoretical gain analysis is performed where the multiple access system's performance is derived from the lattice parameters.

Lattice decoding for joint detection in direct-sequence CDMA systems
A new joint detection method based on sphere packing lattice decoding is presented in this paper. The algorithm is suitable for both synchronous and asynchronous multiple access direct-sequence code-division multiple-access (DS-CDMA) systems, and it may jointly detect up to 64 users with a reasonable complexity. The detection complexity is independent of the modulation size and large -PAM or -Q...
متن کاملAutomatic speech recognition using acoustic confidence conditioned language models
A modi ed decoding algorithm for automatic speech recognition (ASR) will be described which facilitates a closer coupling between the acoustic and language modeling components of a speech recognition system. This closer coupling is obtained by extracting word level measures of acoustic con dence during decoding, and making coded representations of these con dence measures available to the ASR n...
متن کاملComparison of Multiple System Combination Techniques for Keyword Spotting
System combination is a common approach to improving results for both speech transcription and keyword spotting—especially in the context of low-resourced languages where building multiple complementary models requires less computational effort. Using state-of-the-art CNN and DNN acoustic models, we analyze the performance, cost, and trade-offs of four system combination approaches: feature com...
متن کاملDiversity gain of lattice constellation-based joint orthogonal space-time block coding
It is generally thought that space-time block codes (STBCs) can obtain no more than full space diversity. In this paper, we propose a new construction method of joint orthogonal STBCs based onM dimensional lattice constellations for obtaining space and time diversities simultaneously. By deriving the Chernoff bound of error probability, we prove the exact diversity gain of the proposed code is ...
متن کاملJoint Lattice Decoding Achieves the Optimal Diversity-Multiplexing Tradeoff of Multiple Access Channels
In this correspondence, the optimality of LAttice Space-Time (LAST) coding and decoding in the high signal-to-noise ratio regime of outage-limited multiple access channels (MACs) is established. More specifically, it is shown that mod-Λ LAST coding and minimum-mean-square-error generalized-decisionfeedback-equalizer (MMSE-GDFE) decoding achieve the optimal diversity-multiplexing tradeoff of MAC...
