Space-time coded systems with joint transmit and receive antenna selection
(IEEE, 2007)
This paper studies performance of space-time coded (STC) systems with joint transmit and receive antenna selection over multiple input multiple output (MIMO) flat and frequency-selective (FS) fading channels. Specifically ...
Iterative channel estimation techniques for uplink MC-CDMA systems
(IEEE, 2007)
In this work maximum likelihood (ML) channel estimation for uplink multicarrier code-division multiple-access (MC-CDMA) systems is considered in the presence of frequency fading channel. The expectation-maximization (EM)- ...
Distributed estimation with channel estimation error over orthogonal fading channels
(IEEE, 2007)
We study distributed estimation of a source corrupted by an additive Gaussian noise and observed by sensors which are connected to a fusion center with unknown orthogonal (parallel) flat Rayleigh fading channels. The fading ...
Channel estimation for MIMO-OFDM systems in fixed broadband wireless applications
(IEEE, 2007)
Systems employing multiple transmit and receive antennas known as multiple input multiple output (MIMO) systems can be used with OFDM to improve the resistance to channel impairments. Thus the technologies of OFDM and MIMO ...
