Pilot design for underwater MIMO cosparse channel estimation based on compressed sensing
International Journal of Distributed Sensor Networks, 2021 In multiple-input multiple-output–orthogonal frequency-division multiplexing underwater acoustic communication systems, the correlation of the sampling matrix is the key of the channel estimation algorithm based on compressed sensing. To reduce the cross-

Channel Estimation for Spatial Modulation [PDF]
IEEE Transactions on Communications, 2014 In this paper, a novel channel estimation (CE) method is proposed for spatial modulation (SM), a unique single-stream multiple-input-multiple-output transmission technique. In SM, there is only one transmit antenna being active at any time instance. While this property completely avoids inter-channel interference, it results in a challenge to estimate ...

Distributed estimation over parallel fading channels with channel estimation error
2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008 We consider distributed estimation of a source observed by sensors in additive Gaussian noise, where the sensors are connected to a fusion center with unknown orthogonal (parallel) flat Rayleigh fading channels. We adopt a two-phase approach of (i) channel estimation with training, and (ii) source estimation given the channel estimates, where the total

Channel estimation with noisy entanglement [PDF]
Physics Letters A, 2001 We analyze the Pauli-channel estimation with mixed nonseparable states. It turns out that within a specific range entanglement can serve as a nonclassical resource. However, this range is rather small, that is entanglement is not very robust for this application.

Channel estimation using feedback [PDF]
2008 IEEE International Symposium on Information Theory, 2008 It is well known from the information theory literature that in the presence of a memoryless channel, as well as some channels with memory, the existence of feedback does not improve channel capacity, but can contribute dramatically to the simplification of the encoder and the decoder.
