Reliable Adaptive Modulation and Interference Mitigation for Mobile Radio Slow Frequency Hopping Channels

reportActive / Technical Report | Accession Number: ADA500343 | Open PDF

Abstract:

The Long Range Fading Prediction algorithm for Slow Frequency Hopping SFH systems is proposed and demonstrated to enable combined Adaptive Modulation and adaptive Frequency Diversity to mitigate the effects of fading and partial-band interference. Significant performance gains are demonstrated relative to non-adaptive methods in realistic mobile radio SFH channels where the total bandwidth does not exceed approximately 15 times the coherence bandwidth.
