Frequency estimation in multipath Rayleigh-sparse-fading channels.

Frequency estimation in multipath Rayleigh-sparse-fading channels.

Maximum-likelihood (ML) data-aided frequency estimation in multipath Rayleigh-fading channels with sparse impulse responses is investigated. We solve this problem under the assumption that the autocorrelation matrix of the pilot signal can be approximated by a diagonal matrix, the fading of differen...
