Multi-user Multi-carrier Underwater Acoustic Communications | IEEE Conference Publication | IEEE Xplore
Source: ieeexplore.ieee.org
Article summary:
1. This article discusses the design of a multi-user system that uses multi-carrier modulation in the form of orthogonal frequency division multiplexing (OFDM).
2. The transmission and detection method combines OFDM with direct-sequence spread spectrum, and coding is employed across carriers to provide multi-user interference suppression.
3. The performance of the system is demonstrated using recordings from the Mobile Acoustic Communication Experiment (MACE'10), showing that it can operate in a multi-user interference scenario while maintaining low computational complexity.
Article analysis:
This article appears to be reliable and trustworthy, as it provides detailed information about the design of a multi-user system that uses multi-carrier modulation in the form of orthogonal frequency division multiplexing (OFDM). The authors present a transmission and detection method that combines OFDM with direct-sequence spread spectrum, and demonstrate its performance using recordings from the Mobile Acoustic Communication Experiment (MACE'10). The article also provides evidence for its claims by citing relevant research papers.
The only potential issue with this article is that it does not explore any counterarguments or alternative approaches to designing a multi-user system using OFDM. However, this does not detract from its overall reliability or trustworthiness, as it still provides an accurate description of the proposed system and its performance.
