5. Conclusion

The RPS algorithm provides a robust solution for selecting optimal FM transmit frequencies. Selection can be

based upon minimum noise level or averaged minimum noise level. Dividing the FM band into smaller divisions

prevents environmental noise from dominating the selection criteria. The RPS algorithm is easily implemented on

the host and is flexible enough to accommodate memory-constrained applications.

In strong, weak, and multipath signal environments, RPS consistently selects two to four stations that show good

performance. By automating the frequency selection process, users can easily transmit on the optimal frequencies

without any manual scanning.
