A novel least mean squares (LMS) method that exploits sparsity level information for sparse channel estimation is presented and studied in this paper. This method utilizes the channel sparsity level information by incorporating a penalty term into the cost function and has better performance than the compared methods which do not take into account the(More)
Autonomous navigation for spacecraft is not possible using two-way tracking today, but it is crucial during critical event such as when a spacecraft inserts into orbit around a planet in deep space exploration. As the Deep Space Atomic Clock (DSAC) diminishes in size and increases in stability, the accuracies of one-way radiometric observations are improved(More)
