Channel estimation or prediction for UWA?

2013 MTS/IEEE OCEANS - Bergen, 2013
UnderWater 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.

Blind noise and channel estimation

Proceedings of the Tenth IEEE Workshop on Statistical Signal and Array Processing (Cat. No.00TH8496), 2002
In the classical methods for blind channel identification (subspace method, TXK, XBM) (Moulines et al, 1995; Tong et al, 1994; Xavier et al, 1997), the additive noise is assumed to be spatially white or known to within a multiplicative scalar. When the noise is non-white (colored or correlated) but has a known covariance matrix, we can still handle the

Channel sensing strategy for channel load estimation

Proceedings of the 14th ACM international conference on Modeling, analysis and simulation of wireless and mobile systems, 2011
The emergence of multi-channel wireless networks and cognitive radio networks has rendered dynamic channel selection an important task, and many existing channel selection schemes factor in the amount of wireless activities that take place in each channel, or channel load, to achieve load balance and maximize the utilization of wireless resources.

Channel Estimation Using LS and MMSE Estimators

International Journal of Scientific Research, 2012
This 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
