FHSS signal sparsification in the Hermite transform domain

2016 24th Telecommunications Forum (TELFOR), 2016
Signal sparsity is exploited in various signal processing approaches. The applicability ranges from compression, signal classification, coding, etc. Finding a suitable basis where the signal exhibits a compact (sparse) support is a challenging task and the result mainly depends on the signal nature.

Chirp Interference Mitigation for FHSS Communication Based on Compressive Sensing

2018 27th International Conference on Computer Communication and Networks (ICCCN), 2018
A challenge in frequency hopping spread spectrum (FHSS) communication chirp interference mitigation is the requirement of a high sampling rate for wideband FHSS signal. We demonstrate that we could filter out the interference in the system after compressed sampling. Using different sparsity feature of the FHSS signal and the chirp interference, a chirp
