  Abstract

Compressed sensing-based channel estimation is effective for doubly-selective and sparse channel, but it requires the optimization of the pilot pattern. The proposed scheme introduces an indicator of overall mutual coherence, and utilizes the existing equi-spaced pattern and adds a limited number of pilot tones for compressed channel estimation. The simulation results shows that the proposed scheme outperforms the random pilot pattern with only about 3% pilot overhead.
