Implication

This research investigates generalized code index modulation for spread spectrum, demonstrating improved performance in energy efficiency and bit error rate.

Key Points

The proposed GCIM-AFDM-SS scheme improves energy efficiency in spread spectrum systems.
Numerical results show that the proposed system outperforms classical AFDM spread spectrum approaches.
A low-complexity maximal ratio combining method simplifies the decoding process.
An upper bound on the bit error rate highlights the performance benefits of the GCIM-AFDM-SS system.
