Multi-scale multi-lag channel estimation via linearization of training signal spectrum and sparse approximation

Multi-scale, multi-lag (MSML) models are adopted for time-varying (ultra)-wideband channels that are relevant for underwater acoustic, radar and ultrawideband radio applications. MSML channels are characterized by a limited number of paths, each parameterized by a delay, Doppler scale, and attenuati…
