Data Selective Rake Reception for Underwater Acoustic Communication in Strong Multipath Interference

Journal of Electrical and Computer Engineering, 2017
In underwater acoustic communication (UAC), very long delay waves are caused by reflection from water surfaces and bottoms and obstacles. Their waves interfere with desired waves and induce strong multipath interference.

A Viterbi Decoder under Class A Modeled Noise in Shallow Water

Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022
A traditional Viterbi decoder is primarily optimized for additive white Gaussian noise (AWGN). With the AWGN channel, it offers good decoding performance. However, the underwater acoustic communication (UAC) channel is extremely complicated. In addition to white noise, there are a variety of artificial and natural impulse noise that occur suddenly. The

Research and Implementation of Turbo Coding Technology in High‐Speed Underwater Acoustic OFDM Communication

Journal of Robotics, Volume 2022, Issue 1, 2022., 2022
It is demonstrated that the fully parallel turbo decoding algorithm can achieve an approximate error correction decoding performance when 36 iterations are used and when the log‐map algorithm with 6 iterations is used. By comparison, it is shown that it can achieve much higher decoding rates than the log‐map algorithm for various frame lengths of LTE ...

MMW‐NOMA: An Uplink NOMA Communication System Based on the Node Pairing Algorithm of Maximum and Minimum Weight in Underwater Acoustic Networks

Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022
In orthogonal multiple access (OMA) communication systems, resources are allocated to numerous users based on time, frequency, or code domains. The low bandwidth of the underwater acoustic network limits the number of nodes that can be supported by the OMA system, due to limited resources.
