Area of Science:

  • Electrical Engineering
  • Signal Processing
  • Underwater Acoustics

Background:

  • Underwater acoustic channels present significant challenges for wireless communication due to multipath propagation and Doppler effects.
  • Direct-sequence spread spectrum (DSSS) is a robust modulation technique, but its performance degrades in harsh underwater environments.
  • Conventional receivers like RAKE struggle with complex channel conditions, necessitating advanced solutions.

Purpose of the Study:

  • To propose a novel receiver architecture for DSSS transmissions in underwater acoustic channels.
  • To improve receiver performance and reduce computational complexity compared to existing methods.
  • To address the challenges posed by large Doppler disparities in underwater acoustic environments.

  • A per-survivor processing (PSP) structure is employed at the symbol level to manage computational complexity by limiting the number of states.
  • Sparse channel estimation is performed at the chip level using the orthogonal matching pursuit (OMP) algorithm.
  • A two-dimensional dictionary incorporating path delay and Doppler scaling factors is utilized for enhanced channel estimation.

Main Results:

  • The proposed receiver demonstrates a significant performance improvement over the conventional RAKE receiver.
  • The combination of PSP detection and sparse channel estimation achieves a favorable balance between performance and computational complexity.
  • The receiver maintains excellent performance even in challenging underwater channels with substantial Doppler variations across different paths.

Conclusions:

  • The proposed PSP receiver with sparse channel estimation offers a superior solution for DSSS in underwater acoustic communications.
  • The method effectively mitigates the impact of multipath fading and Doppler spread.
  • This approach provides a robust and efficient receiver for reliable underwater data transmission.
