Channel estimation or prediction for UWA?
2013 MTS/IEEE OCEANS - Bergen, 2013UnderWater Acoustic (UWA) channels are narrow bandwidth and typically affected by some interference due to propagation, Doppler effect, noise and possible disturbing signals originated by different acoustic sources. Orthogonal Frequency Division Modulation (OFDM) is an effective answer to such impairments.

Capacity estimation of MIMO ionospheric channels
IET 11th International Conference on Ionospheric Radio Systems and Techniques (IRST 2009), 2009The purpose of this paper is to investigate the feasibility of a HF MIMO system considering polarization diversity channel. While the ionospheric channel associates most of the time the presence of two complementary magneto ionic modes, a 2times2 MIMO configuration is studied. To be easily installed, such an HF MIMO system should include closely spaced

Channel Estimation Using LS and MMSE Estimators
International Journal of Scientific Research, 2012This paper focuses on the channel estimation techniques that are based on the block-type pilot arrangement. Once we establish reliable and practical channel estimation schemes for this type of pilot arrangement. In wireless OFDM transmission using pilot carriers and compare the bit error rate performance by using MMSE and LSE algorithms. Thus comb type
